1) Darius is making picture frames. To make a frame, Darius starts with a square piece of cardboard that is 12 inches long on each side. Then he cuts out a square hole in the center. The size of the square hole depends on the picture he is framing. 12 in. .) s = length (in.) of one side of the square hole 1) Which expression represents the area of the frame in square inches? (12 - 8) 122 - 82 (8 - 12) 8? - 12

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.
