A group of randomly selected Apple Valley High School students were asked to pick their favorite gym class. The table below shows the results of the survey. There are 528 students at Apple Valley High School. Based on the data, what is the most reasonable estimate for the number of students at Apple Valley High School whose favorite gym class is bowling?

With out knowing the functions you have to chose form, this could be one.y = 5.00xx = hours worked and y = the money he will earn.

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.
