Question

Given f(x) = x2 - x3, find f(-10).

Answer 1

Please, use the symbol "^" to denote exponentiation.

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

f( -10) is found by substituting -10 for x in the given equation (immediately above):

f( -10) = ( -10)^2 - ( -10)^3, or -100 + 1000, which equals 900.

Answer 2

The answer is 1100

Explanation:

f(x) = x2 - x3

f(-10) = (-10)2 - (-10)3

f(-10) = 100 - (-1000)

f(-10) = 100 + 1000

f(-10) = 1100
