Finding unit Rates When the denominator of a rate is 1, we call the rate a unit rate. We usually use the key word per or
the division symbol / to indicate a unit rate. For example:
If a student earns $8.50 per hour, it is the same as $8.50/hour, and means $8.50 for every 1 hour of
work.

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
