Question

f(x)=2x-1and g(x)=sqrt(x), find g(f(x))

Answer 1

\[g(f(x))=g(2x-1)=\sqrt{2x-1}\]

Answer 2

@satellite73 why is g(2x-1) sqrt(2x-1) instead of 2*sqrt(x)-1?

Answer 3

@livelaughlilz You have to substitute the value of
\[f(x)=2x-1\]
In place of

x

in

\[g(x)=\sqrt(x)\]

Answer 4

oh so the "x" becomes "2x-1"

Answer 5

Exactly :)

Answer 6

thanks
