If f(x) = -x^3 + 2x^2 - 3,
f(2) = - (2)^3 + 2(2)^2 -3
= -8 +2*4-3
= -8+8-3
= -3

Answer:
4 and 6
Step-by-step explanation:
Judging by the table and how x = 1 and y = 2, you can estimate that y is twice as much as x.
This is supported by the equation, if you take 2 and multiply it by x (1) and take 3 and multiply it by y (2), then add the 2x1 (2) and 3x2 (6), you should get 8.
Step-by-step explanation:
|5x+9|-5x-9
5(1)+9-5(1)-9
5+9-5-9
=0
