you are given a positive number p, but you are not told what the specific value of p is. a vertical light beam comes from high above the plot of f[x] = x^2/(4 p) and bounces off the curve at a given point point {a, f[a]}. you are not told what the specific value of a is. calculate in terms of p the point at which the reflected beam crosses the y-axis.
