Question

What is the domain of the values shown on the table? What does the domain represent?

A) D: {0 ≤ x ≤ 12}; The domain represents the amount of gas used.

B) D: {0 ≤ y ≤ 360}; The domain represents the amount of gas used.

C) D: {0 < x < 12}; The domain represents the number of miles the car can travel.

D) D: {0 < y < 360}; The domain represents the number of miles the car can travel.

Answer 1

Option A) D: {0 ≤ x ≤ 12}; The domain represents the amount of gas used

Explanation:

Let

x ----> number of gallons used (independent variable)

y ---> number of miles remaining (dependent variable)

we know that

The domain of a function is the set of all possible values of x

so

The domain represents the amount of gas used

D: {0 ≤ x ≤ 12}
