hello. I have to do test corrections and I've been trying to figure this out so long so please help :)
I'm trying to figure out if f(x)=7x-12, what is the indicated value if f(-13)?

simply plug in -13 for x:
7(-13)-12
-103
there's your answer.
Hope that helps!

Substitute -13 for x. You get f(-13) = 7(-13) - 12 = -91 - 12 = -103.

Plug in -13 for x.
So it would be
f(-13)=7(-13)-12
-91 -12
-103 is your answer.
Ahh
but this is not trig?

f(x) = 7x -12
F(-13) means x=-13
so it is 7 x 13 - 12 or -103
f(-13) = -103

come on girl!
Just sub in -13 for x, so 7 x (-13) - 12, can you do that?
Sounds like you will be an artsie
