Draw a strip diagram like the one in Figure 2.60 to show that Adam has read 5/6 as many books as Joseph this year. Explain briefly. Based on your strip diagram in part (a), write a sentence in which you use a fraction to describe how the amount of books that Joseph has read compares with the amount of books that Adam has read.

It would be 0 at least it should be

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.
