The graph of this quadratic function is a parabola. What is the equation of the axis of symmetry?

y=x^2+-6x+5

The answer to your question is x = 3

Step-by-step explanation:

Equation

                               y = x² + 6x + 5

Process

1.- Find the vertex

                              x² - 6x     = y - 5

                              x² - 6x + (3)² = y - 5 + (3)²

                              (x - 3)² = y - 5 + 9

                              (x - 3)² = y + 4                                

Vertex = (3, -4)

2.- It is vertical parabola and the axis of symmetry is parallel to the y-axis and crosses the point 3.

The equation of the axis of symmetry is   x = 3
