Question

Three functions are given below: f(x), g(x), and h(x). Determine the axis of symmetry for each function. Show all calculations. 

Answer 1

f(x) = -2(x − 4^)2+ 2

The vertex is (4,2)

so the axis of symmetry is  is x=4

g(x) = 5x^2− 10x + 7

       h= -b/2a = 10/2(5) = 10/10 =1

The axis of symmetry is at x=1

h(x)  the axis of symmetry is at x=-2
