# How do you find the axis of symmetry, and the maximum or minimum value of the function #y = –3(x + 7)^2 – 10#?

##### 1 Answer

#### Explanation:

This is the vertex form of equation type

If you were to square the brackets and multiply by the -3 the

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The coordinates of the vertex can be read directly from the given equation but you will need to 'tweak' it a bit.

Given:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The axis of symmetry passes through the vertex and is parallel to the x-axis (for a quadratic in x as is this one)
