Hello, could you help me understand how to solve these problems. Thank you.

FUNCTIONS Q Let f(x) = x2 - 9, g(x) = 2X + 3 and h(x) = x - 3. Find each of the following. a) (f + g)(x) b) (f/h) (x) c) g(f(x)) d) fig(h(x))) e) (g - h)(8) f) h(f(-2)) 2. State the domain, range and zeros of each of the following. a) y = Ixl b) 107 N 2 3H 1 3' Determine whether the graph of each of the following equations is symmetric with respect to the xaxis, yaxis, origin, the line y = x or none of these. a) y:-8X b) x1+W:4 0) y:-IX\\ 4. Show, algebraically, that f(x) = 4X 9 and 30:) = (X + 9)/4 are inverse functions, 5. Find a rule for the inverse of f(x) : x3 + 1. Then graph hoih x) and f'(x) on the same coordinate plane
