What is a quartic function whose only real zeros are the following?
x=-3 and x = 2
y=x4 + x3 - 5x2 + x
y=x4 + x3 + 5x2 + x
y=x4 + x3 - 5x2+x-6
y= x4 + x3 - 5x2 + x + 6

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
