The image of a parabolic mirror is sketched on a graph. The image can be represented using the function y= -1/8 X2+2, where x represents the horizontal distance from the maximum depth of the mirror and y represents the depth
of the mirror as measured from the X-axis. How far away from the maximum depth is a point on the mirror that is7/8
inches in depth?
O 3 inches
O 4 inches
O 5 inches
6 inches
