You want to know the opinion of home schooled students across America on whether they prefer to learn at home versus school with other students. You obtain a list of all homeschooled students students and mail a survey to random 7500 students of the 4195 responded and 39% say they refer to learn at home. Which of the following statement true?

I’m not gonna do that

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.
