Hi, there-- Your Problem: Evaluate the functions when x=2, x=0 h(x) = 8x + 7 Solution: To evaluate the function for x=2, substitute 2 for the variable x in the function. You get h(2) = 8(2) + 7 Now simplify the right hand side. h(2) = 16 + 7 h(2) = 23 It's that straightforward. Now you try the rest. Feel free to email me if you want to check your work.
