Answer:
The linear function is
The reasonable domain is
Step-by-step explanation:
Let
x ----> the time in hours
y ---> the distance in miles
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem
The slope is
The y-intercept is
substitute
<em>Find the domain for x</em>
For y=120 miles
Find the value of x
substitute the value of y in the linear equation and solve for x
therefore
The domain is the interval [0,2]
