-V7+43
√7 + 4/5
b.
-V7-413
d. 7-43
a.

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 : )

answer: d. $20

step-by-step explanation:

just took the test

your answer would be 12
