(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Write the equation of a parabola passing through the point (2,-2√2) and opening to the right.

2. Relevant equations

Parabola with a horizontal axis and vertex (0,0) y^2 = 4cx

3. The attempt at a solution

Since the parabola opens right I will use the equation y^2 = 4cx

I will let x = 2 and y = -2√2

y^2 = 4c(2)

(-2√2)^2 = 4c(2)

2 = 4c(2)

2 = 8c

1/4 = c

y^2 = 4(1/4)x

y^2 = x

* The answer in my student solution mannual says the correct answer should be y^2 = 4x. When I graph this, my graphs supports this answer, where did I go wrong?
