Consider the given function.
f(x) = x^2 -14x -72
What are the zeros and axis of symmetry for the graph of the function?
A.
zeros: x = -9 and x = -8;
axis of symmetry: x = -7
B.
zeros: x = -18 and x = 4;
axis of symmetry: x = -7
C.
zeros: x = 9 and x = 8;
axis of symmetry: x = 7
D.
zeros: x = -4 and x = 18;
axis of symmetry: x = 7

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
