You forgot picture.So I can't explain that

Let's check if (3 , 6) is the point of intersection of the given lines ~

and

If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.



So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
Answer:
d
Step-by-step explanation:
for this function you have to replace the function of g(x) where there's x in the function f(x) that's what the expression f.g(x) means and so this is going to be
3(x²+1)+2
I hope this helps
