Answer:
f(x)- x=4 h(x)- x= -2
Explanation:
For f(x) you put it into the graphing calculator and look at the table to find the vertex. The axis of symetry is the line that passes through the vertex, so it is x= the x value from the vertex.
For h(x) you find the vertical line that passes through the vertex, in this case it is x= -2.
