Hello, I need help on my Mathematics 30-1 (Pre-calculus) Quiz 7.3 Questions #3-#5 and Numerical Response 2

3. If h(x) = f(x)8 (x), then the true statement is A. h(x)f(x) = 8(x) B. h (x) f (x ) = 8(x) f( x ) C. g (x) = h (x ) D. f ( x) = 8 (x) h(x ) Hint: Rearrange the equations. 4. If f( x) = Vx+ 5 and g(x) = 1 -x2, the domain of h(x) = f(x) g(x) is A. x 2 . - 5 B . x 2 C. x 2 D. X ER Hint: Note the domain of f(x). 5. The function h(x) = f(x) g(x) . where f(x) = x(x+ 2) and g(x) = x(x- 2), has non- permissible values that correspond to which of the following on the graph of h(x)? A. vertical asymptotes B. points of discontinuity C. there are no non-permissible values for h(x) D. a vertical asymptote and a point of discontinuity Hint: Simplify h(x) to determine the type(s) of non-permissible values. Numerical Response 2. If f( x) = 2+ v x and 8(x) = 14 - 3x|, then (f . 8)(4) = Hint: Combine, then substitute. Or, find f(4) and g (4) first
