$3.19
B -$3.19
C $4.50
D -$4.50

B

Step-by-step explanation:

If the charge for five cards was -15.95, the charge for one card is -3.19 because (-15.95)/5 = -3.19

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
