The cost (c) of renting a truck for $30 and then paying $2 per mile (m). write the function rule

f(x) = 2m + 30

Step-by-step explanation:

Since the truck costs 30 dollars to rent plus the 2 dollars per mile to find the function rule you use an equation that makes the 2 dollars per mile the dependent variable.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
