Question

Let f(x)= square root x, g(x)=cos x

Find f(g(x)) and g(f(x))

Answer 1

\(f(x)=\sqrt x\)
\(g(x)=cosx\)
To find f(g(x)) what you have to do is u shud replace x in f(x) with g(x).
Can u do that @xkat?

Answer 2

is the answer cos square root of x?

Answer 3

hmm no.
\(f(g(x))=\sqrt{cosx}\)
getting it @xkat?

Answer 4

so then g(f(x)) is cos square root of x right?

Answer 5

exactly:)

Answer 6

okay thanks ! I always get those switched up.

Answer 7

yw:) That's something likely to happen.:)
