Wendy is logging the number of video game levels she wins per hour. she has determined the function to be f(x) = 6x + 9, where x represents hours and f(x) represents the number of video game levels won. which of the following options describes the restrictions to the domain and range correctly?

a) domain, nonnegative values; range, values greater than −1.5
b) domain, nonnegative values; range, values less than −1.5
c) domain, nonnegative values; range, values greater than or equal to 9
d)domain, nonnegative values; range, values less than or equal to 9

Let

x--------> represents hours

f(x)------> represents the number of video game levels won

we know that

this is the equation of a line

The slope m is equal to

the domain is the interval-----------> [0, ∞)

the range is the interval--------> [9, ∞)

using a graph tool see the attached figure

therefore

the answer is the option

C) Domain, nonnegative values; range, values greater than or equal to 9

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
