You got 3x^2 + 12 , but what was the question ???
Are you supposed to find something like f(g(x)) ?
Are you solving ?
Question 1
A)
f(x)=2^x and g(x)=3−x
I got 3x^2+12 don't know if im right
B) i need help for this
f(x)=sinx and g(x)=x

Finding the composite function
Still not totally clear what you mean, is it
f(g(x)) or g(f(x)) ------ not the same!
I will assume
f(g(x))
= f(3-x)
= 2^(3-x)
I have no idea how you got 3x^2 + 12
same with B
if f(x) = sinx and g(x) = x
then
f(g(x))
= f(x)
= sinx
f(g(x)) or g(f(x)) ------ not the same!
I will assume
f(g(x))
= f(3-x)
= 2^(3-x)
