Question

Given F(x) = x²- 8x + 8, find F(-5)

Answer 1

73

Explanation:

To find F(-5), we need to substitute x = -5 into the expression for F(x) and simplify:

F(-5) = (-5)² - 8(-5) + 8

F(-5) = 25 + 40 + 8

F(-5) = 73

Therefore, F(-5) is equal to 73.

Answer 2

The answer to
`F(x)=x^2-8x+8,` when
`F(x) = F(-5)` is F(-5) = 73.

In short, F(-5) = 73.

Explanation:

How can we solve this problem?

We know the equation is
`F(x)=x^2-8x+8`. And we know F(x) is equal to F(-5).

So, we know we must substitute -5 into the equation, F(x) = x^2 - 8x + 8.

`F(-5)=(-5)^2-8(-5)+8`

`F(-5)=(-5)^2+40+8`

`F(-5)=(-5)^2+48`

`F(-5)=25+48`

`F(-5)=73`

So, the answer is F(-5) = 73.
