Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation

is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:

Then, for our case the x position of the given parabola, is:

Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3

Answer:
56.6 °
Step-by-step explanation:
