Question

Find the directrix of the parabola y = (1/8)(x – 5)2 - 3.

Answer 1

I have no idea. Quick question for you though since we are working on similar stuff. How do I write this equation in graphing form: y=2x^2-12x+19

Answer 2

Answer:

y= -5

Step-by-step explanation:

rewrite as standard form    $4.2(y-(3-))=(x-2)^{2}$

(h.k) = (2, -3), P=2

y= -3 -P

y= -3 -2

y= -5
