Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest; x=1 would be smaller than x=5). f(x) g(x) h(x) f(x) = (x + 4)2 + 1 g(x) = 2x2 − 16x + 15 graph of 2 times the quantity of x minus 1 squared, minus 3
