axis of symmetry

#### Explanation:

This is a quadratic equation that has been changed such that it is in vertex form. You virtually read the values you are asked to find almost directly from this.

Consider the -1 from

Multiply this by negative 1 giving

So the axis of symmetry is the line parallel to the y-axis defined by

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As

We already have the value of x all we need now is the value for y.

As it happens this is the value of the constant in the equation

So
