For this case we have the following function:
[tex]f (x) = x ^ 2-8x + 5
[/tex]
To find the value of f (-1) we must substitute x = -1 in the given expression.
We have then:
[tex]f (-1) = (- 1) ^ 2-8 (-1) +5
[/tex]
Rewriting we have:
[tex]f (-1) = 1 + 8 + 5
f (-1) = 14[/tex]
Answer:
The value of the function f (x) in evaluated for x = -1 is given by:
[tex]f (-1) = 14
[/tex]
option 4
