Question

I really need help !
-f(x) = 3x + 5, g(x) = 6x2
Find (fg)(x).

-Describe how the graph of y= x2 can be transformed to the graph of the given equation.
y = (x - 13)2 + 6

-f(x) = 3x + 5, g(x) = 6x2
Find (fg)(x).

-Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y = two divided by x squared + 9

-Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.
f(x) = x2 - 3 and g(x) = square root of quantity three plus x
Sorry, I honestly need your assistance.
