Question

Let f(x) = x2-4 and g(x) = x+6. a. Find f(g(x)). b. Find g(f(x)).

Answer 1

f(g(x)) = (x+6)^2-4
g(f(x)) = x^2-4 + 6

Answer 2

.... -.- *facepalm*

Answer 3

myin, check my ansswer, tnx :)

Answer 4

it can all be simplified btw, mad u can do the simplification

Answer 5

I got something.. but I'm pretty sure it's wrong...

Answer 6

what is x+6^2

Answer 7

\[f(g(x))=(x+6)^2-4\]
this is what bahrom typed there

Answer 8

that ^ just means we have a power

Answer 9

How do i simplify x+6^2 is it mean 2x^2 + 36?

Answer 10

no no

Answer 11

\[(x+6)^2=(x+6)(x+6)=x(x+6)+6(x+6)=x^2+6x+6x+36=x^2+12x+36\]

Answer 12

\[(x+6)^2=x^2+12x+36\]

Answer 13

Ohhhhh I got it wow
