If f(x) = x^3-2x, find f(-2).

f(-2) = -4

Step-by-step explanation:

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

Let x = -2

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

       = -8 +4

        = -4

The correct/valid answer is f(-2) = -4

Step-by-step explanation:

><><><><><><<><><><><><

Step 1:

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

Step 2: Determine what x will be

x will be = -2

Step 3: Multiply by -2

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

Step 4: Solve the equation

= -8 +4  

= -4

Final f(-2) = -4
