Question

Kala is a software saleswoman. Let P be Kala's total pay (in dollars). Let N be the number of copies of English is Fun she has sold. Kala has 140 copies availableto sell. Suppose that P = 20N + 4200 gives P as a function of N for these available copies.Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.

Answer 1

• Domain, is the number of copies kala has sold.

,

• Range, is Kala's total pay in dollars.

STEP - BY - STEP EXPLANATION

What to find?

Correct description of the values in both the domain and range of the function.

Given:

Domain

The domain are sets of x-values into the function f(x).

Range

The range of a function is the set of values that the function assumes.

Given that :

`P=20N+4200`

Since N is the number of copies sold, this assumes various set of input values.

Whenever any set of N values are input, we get an output of P.

Therefore, since N is the input values and P is the output values, then by definition, N is the domain and P is the range.

Hence,

Domain is the number of copies kala has sold.

Range is Kala's total pay in dollars.
