Which of the following equations has a maximun? a. y=3x-1
b. y=4x^2+4
c. y=x^2
d. y=-7x^2-1

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
