Question

Given f(x) = x^2-2x+5
Find f(-2)

Answer 1

f(-2) = 13

Explanation:

f(x) = x² - 2x + 5

Yo find f(-2) substitute the value of x that's - 2 into f(x) that is for every x in f (x) replace it with - 2

So we have

f( - 2) = (-2)² - 2(-2) + 5

= 4 + 4 + 5

= 8 + 5

We have the final answer as

f(-2) = 13

Hope this helps you
