Question

If f of x is equal to 5 x square - 4 x + 5 find f of 1 + F of -1 + F of zero

Answer 1

Answer:

Step-by-step explanation:

f(x) = 5x^2 - 4x +5

f(1) = 5(1)^2 - 4(1) + 5

f(1) = 6

f(-1) = 5(-1)^2 - 4(-1) + 5

f(-1) = 14

f(0) = 5(0)^2 - 4(0) + 5

f(0) = 5

f(1) + f(-1) + f(0) = 6+14+5

                       = 25
