Please help answer

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. 1 x = 7 , y z- 9 4 B. x 2 7 1 2. YER C. x ER, y 2 - 4 D. XER, y ER 4. Identify the false statement. A. if h (x) = g(x) +g(x), then 28(x) = h(x) B. if h ( x) = f( x) + g(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 ) + g (x) = h(x), then f(x) = h(x)- 8(x) Numerical Response 2. The graph of the function h ( ) = (&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
