If f(x) = (-x)3, what is f(-2)?

-8
-6
6
8

8

Step-by-step explanation:

f(x) = (-x)^3

Let x = -2

f(-2) = (- -2)^3

        = (2)^3

        = 8

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
