Question

Let f(x) = x2 − 8x + 5. Find f(−1)

Answer 1

Answer: 14

Step-by-step explanation:

f(-1) = (-1)^2 - 8(-1) + 5
f(-1) = 1 + 8 + 5
f(-1) = 14

Answer 2

14

Step-by-step explanation:

`f(x)=x^2-8x+5`

now substitute x for -1

`f(-1)=(-1)^2-8(-1)+5`

now solve

`f(-1)=1+8+5`

`f(-1)=14`

there is your answer! hope this helps! :)
