Question 522402: Please help me with this! I don't know how to do this.
I have to write this equation in vertex form.
The vertex of the parabola is the origin. Point P (1,7) lies on the graph of the parabola.
Thank you so much.

I have to write this equation in vertex form.
The vertex of the parabola is the origin. Point P (1,7) lies on the graph of the parabola.
-----
Plot those two points.
------
Form of the equation: y = a(x-h)^2+k
---
(h,k) is vertex
-----
h= 0 and k = 0
y = ax^2
---
Use point) (1,7) to solve for "a":
7 = a*1^2
a = 7
----
Equation:
y = 7x^2
