We are going to make the following definitions:
Symmetry axis: Is the axis that divides the quadratic function into equal parts.
Intersection with the y axis: is the point of the graph (or table) whose coordinate x is equal to zero.
We have then:
For f (x):
Symmetry axis: x = 2
Intersection with y axis: (0, 6)
For g (x):
Symmetry axis: x = 2
Intersection with y axis: (0, 8)
Answer:
