Question

The function c(x) = 0.5x+70 represents the cost c (in dollars) of renting a truck from a moving company, where x is the number of miles you drive the truck Item 21 Question 1 The function c(x) = 0.5x+70 represents the cost c (in dollars) of renting a truck from a moving company, where x is the number of miles you drive the truck

Answer 1

Explanation:

the given function:
`c(x) = 0.5x+70.`

Where C = cost (in dollars) and x is the number of miles you drive the truck.

when we compare the given function by slope- the intercept form y=mx+b, what we get is

Slope m = 0.5 whose fraction can be written as
`(1)/(2)`

And y-intercept b =70.

for us to be able to graph it, we need to plot y-intercept from 70 and then plot some more points by applying or increasing the points by
`(1)/(2)`

the shaded lines on the graph indicates the given function.

cost is at $70 for 0 number of miles. travelled.

Thus;

the Domain: x≥0 and Range :
`C(x)`≥
`70`
