their all negative options. I just didn't notice there weren't there sorry.

replaced x with -4

isn't it g(x)*f(x)*(-4)

are you familiar with these?

actually what i hav studied is that f(x) or g(x) can be written as f or g
and f'g is f multiplied g

I think there's a few ways you can actually do it.

there is also braces for (f'g) separating it from (-4)

those ways can change the entire ans. actually!

yeah

Here's the question is \((g\circ f)(x)\) right?

yeah

Here's the thing:
\[(g\circ f)(x)=g\left( f(x)\right)\\
gf(x)=g(x)\times f(x) \]
right?

that circle between g and f means g "of" f

Still confused? It's the same as before g(f(4))

Same sort of question

I did
g(f(-4)) = 3(4x+7)-5
but that's wrong

so now I'm going through everything again

oh I was doing -4 but I do 1 I guess.

Oh oops it's -4

oh

g(f(-4)) = 3[4(-4)+7]-5

You're doing it right then, why doubt yourself? :P

Yay :)
