A function is a mathematical relationship between the domain and the range, two sets of values. The range is the set of output values that the function produces, and the domain is the set of input values for which it is defined.

What is a function, exactly?

a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

Consider the function f(x) = x^2 as an illustration. This function generates the value f from the supplied value x. (x). This function will return the value 9 if the given value is 3, since 3^2 = 9.

Generally speaking, a function describes the relationship between two sets of values (the domain) (the range). For instance, the relationship between the input value x and the output value f(x) is described by the function f(x) = x^2.

A formula, which is a guide that explains how to calculate the output value for a specific input value, is typically used to express a function. For instance, the function f(x) = x^2 has the formula f(x) = x^2. We just enter the input value into the formula and simplify to determine the output value for a particular input value.

A fundamental idea in mathematics, functions are used to model and describe a wide variety of real-world occurrences. For instance, the quadratic function f(x) = x^2 + 2x + 1 can be used to simulate how an item would move in the presence of gravity. A population's expansion over time can be predicted using the exponential function f(x) = 3^x.

The one-time administration fee is (d) $60

From the question, we have the following parameters that can be used in our computation:

12 months costs $660.

15 months costs $810.

This means that

(x, y) = (12, 660) and (15, 810)

For the one-time administration fee, we have

(x, y) = (0, y)

So, we calculate the slope using

slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

(y - 660)/(0 - 12) = (810 - 660)/(15 - 12)

This gives

(660 - y)/12 = 50

So, we have

660 - y=600

This gives

y = 60

Answer:

16x^8y^3

Step-by-step explanation:

Simplify the expression.

Answer:

[tex]-8x^7(-2xy^3) = 16x^8y^3[/tex]

Step-by-step explanation:

⭐Multiplication rules

⭐ Exponent multiplication rule

⭐ Multiplying two terms with variables

We need to utilize these 3 key points (⭐) when multiplying to terms with variables.

First, let's multiply the coefficients:

-8 * -2 = 16

Next, let's multiply the variables:

[tex]x^7 * xy^3[/tex]

These two variables have the same base (x), so we will add their exponents up.

* remember: if you see a variable without an exponent, it has an exponent of 1 *

[tex]x^7 * x = x^8[/tex]

The variable [tex]y^3[/tex] will stay the same because there is no other y variable.

= [tex]x^8y^3[/tex]

Now, "attach" the variables to the product of the coefficients:

= [tex]16x^8y^3[/tex]

The vertex form of line f(x) = ax² + bx + c  is y = a(x - h)² + k where the vertex is (h, k).

The vertex form of a line is one of the representations of the line in an equation format. Here the line focused on the coordinates of the vertex.

For a line, f(x) = ax² + bx + c, the vertex form is y = a(x - h)² + k; vertex at (h, k).

To convert the general form to the vertex form, the general equation is simplified as below:

y = ax² + bx + c

  = ax² + bx + c + b²/4a - b²/4a

  = a(x² + b²/4a² + b/a) + (c - b²/4a)

  = a(x² + (b/2a)² + 2b/2a) + (c - b²/4a)

  = a(x + b/2a)² + (c - b²/4a)

⇒ y = a(x - (-b/2a))² + (c - b²/4a)

Consider -b/2a = h and (c - b²/4a) = k, then we get

y = a(x -h)² + k; vertex form of the given line.

A geometric sequence is an exponential function. Instead of y=ax, we write an=crn where r is the common ratio and c is a constant (not the first term of the sequence, however). A recursive definition, since each term is found by multiplying the previous term by the common ratio, ak+1=ak * r.

Geometric function theory is the study of geometric properties of analytic functions. A fundamental result in the theory is the Riemann mapping theorem.

Answer:

If each shopping trolley is 1 meter long, and each trolley in the stack adds 0.25 meters, then the total length of the stack will be equal to the length of each trolley plus the length added by each additional trolley in the stack. This means that the total length of the stack will be equal to 1 + 0.25 = 1.25 meters per trolley.

If the stack has a total length of 10 meters, and each trolley adds 1.25 meters to the stack, we can divide the total length by the length added by each trolley to find the number of trolleys that can be stacked in a single line of 10 meters:

10 / 1.25 = <<10/1.25=8>>8 trolleys

Therefore, if each shopping trolley is 1 meter long and each trolley in the stack adds 0.25 meters, a single line of 10 meters could hold a stack of 8 trolleys.

The value of function  (f + g)(x) is 7x² + x - 4.

Here the functions provided are,

f(x) = 4x² - 5x

g(x) = 3x² + 6x - 4

The p addition property of functions (f + g)(x) allows them to be written as,

(f + g)(x) = f(x) + g(x)

In the above equation, we can substitute the values of each function.

(f + g)(x) =  4x² - 5x + 3x² + 6x - 4

We have to combine the similar terms,

(f + g)(x) =  4x² - 5x + 3x² + 6x - 4

Replacing the values of h and k to create the equation of the transformed function gives us; y = [∛(x - 4)] - k

The graph represents a transformation of the parent cube root function.

The parent cube root function is; y = ∛x

In this parent function, we see that the value of h  and k are equal to 0. Where;

h = 0, k = 0 in parent function

Then the graph changes direction at the coordinate (0,0) in parent function.

From the given graph, we can see that it changes direction at the coordinate (4,-1)

This tells us that the graph is shifted by 4 units to the right and then by 1 unit downwards.

Thus, it means that the value of h = 4  and the value of k = 1.
