For the given model of the form y^2 = 4px
A. Determine the value of p.
B. Identify the focus.
C. Write an equation for the directrix.
Express numbers in exact, simplest form.
y^2 = 32x
Solution
y^2 = 32x
Gen : y^2 = 4px
a) 32 = 4p
p = 8
b) Focus : parabola is left facing
So, foci ( 8, 0)
c) directrix: x = -8
