The cost of a camp is $300 for the first week and $125 for each week beyond the first. the total cost can be modeled by the expression 300 + 125(x – 1). what does (x – 1) represent?

x - 1 represents all the weeks of camp, but not including the first week (since it is a different cost)

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.
