Answer to Problem 42PPS
The vertex form of quadratic equation is
Explanation of Solution
Given information:
The quadratic equation is mentioned as
Formula used:
The vertex form of the quadratic equation is in
The axis of symmetry always passes through vertex of parabola which is
Calculation:
Consider the standard form of quadratic equation
Here we will divide the above quadratic equation by
Therefore the quadratic equation becomes
Recall that for the vertex form of the quadratic equation is in
Therefore the vertex form of the quadratic equation is
Therefore
Therefore
Recall that the axis of symmetry always passes through vertex of parabola and the x coordinate of the vertex is the equation of the axis of symmetry.
Therefore the axis of symmetry is vertical line
Therefore the axis of symmetry is
