The ray $y = 2$ strikes $y^{2} = 4 x$ at $A$ and, after reflection, meets the axis at $B$ . The normal at $A$ meets the axis at $C$ . Which are true?

Answer:

B, D

Solution:

$A = (1, 2)$ . The reflected ray passes through the focus $B = (1, 0)$ , and the normal $x + y = 3$ meets the axis at $C = (3, 0)$ .
