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
