Question

A traveler is driving home. He is currently 500 miles from home and he drives 75 miles each hour. Find a function for the traveler's distance from home after x hours.

Answer 1

Answer: f(x) = 500 - 75x

Explanation:

f(x) is the function

500 is the miles away from home

75x is how many miles will pass after x hours

Answer 2

f(x) = 500 - 75x

Explanation:

Since he drives 75 miles each hour, his distance driven can be represented by 75x.

To represent his distance from home, 75x needs to be subtracted from 500.

So, the function will be f(x) = 500 - 75x
