could you help explain how i would be able to solve this so i can have a better understanding?

1. For f(x) = 3x2 + 5 and g(x)=?x2, 3. Verify: 90: + 2} at 900 + 9(2). b. Find {fg}{x}. o. Using the resulting function in (b), show that {f g)(2} = f(2) 9(2). {The work should be different for each side of the equation} d. ls(fg}(0}= (3)63? Explain. e. Find W, hen
