Given the function f(x) = x^2- 2x, find f(-1) and f(1). Based on your answers, determine if the function is even. Explain your reasoning.

f(-1) = 3

f(1) = -1

Step-by-step explanation:

f(x) = x^2- 2x; substitute the value into x

f(-1) = - 2x = - 2(-1) = 1 + 2 = 3

f(1) = - 2x = - 2(1) = 1 - 2 = -1

i think asking google will you get the answer to that question
