They said F(x) later and they give me F(-5) so would i replace -5 with x?

igreen · Answer

$f(x) = |(x^2 - 50)|$

$f(-5) = |(-5^2 - 50)|$

I think you can finish that.

igreen · Answer

Yep, you do.

D. -25

anonymous · Answer

also i meant to say replace x with -5 :p

igreen · Answer

Close.

It has absolute value signs..which makes the value positive.

$f(-5) = |(-5^2 - 50)|$

$f(-5) = |(25 - 50)|$

$f(-5) = |-25|$
