Question

Let f(x) = x2 − 8x + 5. Find f(−1)

Answer 1

Answer:

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! :)

Answer 2

Answer: 14

Explanation:

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