The image of a parabolic mirror is sketched on a graph. The image can be represented using the function y=-3x2 + 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 is inches
in depth?
O 3 inches
4 inches
5 inches
6 inches

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
