Substitute the given values into the formula, and solve for the unknown variable.
A=1/2h(B+b); A=21, B = 2, b = 5
h=?

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 : )
