What is the function of f(g(x)) if f(x)= x^2+1 and g(x)=3x

Step-by-step explanation:

For this composition function, , we should substitute anytime we see an variable in :

whats the

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
