here are a total of 134 foreign language students in a high school where they offer Spanish, French, and German. There are19 students who take French and German,21 students who take French and Spanish,16 students who take German and Spanish, and5 students who take all three languages. If there are 57 Spanish students, 67 French students, and 61 German students, find:a) How many students take French only. equation editorEquation Editorb) How many students take French AND German but not Spanish. equation editorEquation Editorc) How many students take French OR German but not Spanish.

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.
