Question

8. If f(x) = 2x2 - 4x + 5, find the value of f(1) + f(-1) + f(0). solutions ​

Answer 1

ANSWER:

f(1) + f(-1) + f(0) = 19...

STEP-STEP EXPLANATION:

f(1) = 2(1)² - 4(1) + 5

= 2 - 4 + 5

= 3..

f(-1) = 2(-1)² - 4(-1) + 5

= 2 + 4 + 5

= 11...

f(0) = 2(0)² - 4(0) + 5

= 0 - 0 + 5

= 5....

therefore, f(1) + f(-1) + f(0) = 3 + 11 + 5

= 19...
