Answer:
x = 1
Step-by-step explanation:
For a quadratic function
, the axis of symmetry is
.
This comes from using part of the Quadratic Formula for finding zeros of the function:

See the -b/(2a) in the first term? That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function. The axis of symmetry goes through the vertex.
The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.
