To find the slope of the function

To identify the vertex and determine if it's a maximum or minimum

To determine the y-intercept

To calculate the area under the curve

A zero of the function

A maximum point

A minimum point

A point of inflection

Add a constant to both sides

Factor out the leading coefficient

Multiply the entire equation by 2

Divide the entire equation by the leading coefficient
