Https://video. link/w/GixDb (video for context on the problem) How much will it cost to pump 1 LITRE of fuel into the tank (unit rate)

(show work btw)

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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive
