Can someone help me?

A) 27.32            B) 31.88

Step-by-step explanation:

25.30×1.08≈ 27.32 after tax

(25.30×0.08)+(25.30×0.18)+25.30≈31.88 after tax+tip

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
