Step-by-step explanation:

p(x) =  {x}^{3}  - 4x - 5 \\ p( - 2) =  {( - 2)}^{3}  - 4( - 2) - 5 \\  =  - 8 + 8 - 5 \\  =  - 5

Answer:

The answer would be -5.

Step-by-step explanation:

First I plugged in negative 2 for every x in the equation, which gives me:

p(-2) = (-2)³ - (4(-2)) - 5.

We solve for the exponents first, which gives us a total of -8 because we are multiplying -2 by itself 3 times. Then we multiply 4 and -2, which gives us negstive 8. However, the first -8 and the second -8 cancel out because the equation has a - sign in between the two, leaving us with only -5. -5 is the answer.
