Problem: A website describes how to make a parabolic dish with a wok and a microphone attached to the focal point. You have a wok 22 inches wide (shown as vertical on the paper) and 8 inches deep (shown as horizontal). Write an equation that represents the cross section of the wok. Find the location of the microphone as well.
Background info (for anyone asking if I attempted problem): For this one, it was asking to find the focus. I thought the focus was (8,0), so in x = 1/4p * y^2, I subbed in 8 as p and got x = 1/32 y^2. However, one of the points supposed to be on the graph was (8,13), which wasn't on the equation I got. So, I'm sure what I did was wrong.
