Review: Key Features of Quadratic Functions

Also the Max or Min

Always write as an ordered pair (x,y)

When asked to write the value of the Max or Min, write the y value of the vertex

Vertical line that splits the function down the middle

Write your answer as x = k; k is the x value of the vertex

Also called zeros or roots

There can be 2, 1, or no zeros

Write your answer as an ordered pair (x,y); y value will always be 0

The domain will always always always always be (-inf, inf)

Range is the lowest point to the highest point (one of those points will always be infinity)
