Question

if f(x)=since,g(x)=x*2,xER,then find (fog)(x)​

Answer 1

Answer:

The answer is $\sin(x^2)$

Step-by-step explanation:

Given $f(x)=\sin x$ and $g(x)=x^2$

Therefore

         $(fog)(x)=f(g(x))=f(x^2)$, replace x by g(x) in function f

                                        $=\sin(x^2)$, Using $f(x)=\sin x$
