Hello, I need help on my Mathematics 30-1 Quiz 5.1 (Pre-calculus) Questions #3-#5 and Numerical response #2

3. State the domain and range of f(x) if h(x) = f(x) + g(x) and h(x) = x2 + x-1 when g(x) = 2x + 1. A. x 27, y 2-1 B. x 27, YER x ER, y 2 - 4 D. XER, y ER Hint: Graph h(x) and g(x), then subtract function values to determine the graph of f(x). 4. Identify the false statement. A. if h (x) = 8(x) +8(x), then 28(x) = h(x) B. if h (x ) = f(x) +8(x), then g(x) = f(x)-h(x) C. if f( x) - 8(x) = h(x), then g(x) = f(x)-h(x) D. if f ( x) + 8 (x) = h(x), then f(x) = h(x)-8(x) Hint: Use algebra to rearrange the terms in each statement. Numerical Response 2. The graph of the function h(x) = (&f )(x) passes through the point (2, k), the graph of g(x ) passes through the point (2, - 4), and the graph of f(x) passes through the point (2, - 3). The value of k is Hint: Focus on the y-values only. 5. If f(x) = 2x2+ 2, then f(f(x) ) = A. 8x* + 16x2 + 10 B . 4x*+ 8x2 + 10 C. 8x* + 10 D. 4x4 + 10 Hint: Substitute the function into itself
