Yoon buys a box of markers for $2.85, but he has a coupon for 20% off. how much does he save with the coupon?

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

b.-4 units

all you   do is count how many times you move
