Question

A car travels at a rate of 45 miles per hour for 5 hours. Let y be the ostece, in miles, the car travels for a given amount of time, x, in hours. This situation can be modeled by a function What is the domain of the function?

Answer 1

Answer:

The complete question in the attached figure

Let

x ----> the time in hours

y ----> the distance in miles

In this problem we have a proportional relationship between the variables x and y

The linear equation is of the form

The slope or unit rate is the same that the constant of proportionality k

The constant of proportionality is the speed of the car

so

substitute

Convert to function notation

The domain of the function is the interval ---> [0,5]

All real numbers greater than or equal to 0 hours and less than or equal to 5 hours
