A function written in the form ---> , where (h,k) the vertex.
Given: , we complete the square:
, Add , and also subtract so the expression won't change.
*Note: How we get ? Take half of the middle term constant (which in this case is "1") then squared it. --->
Continuing;
----> ,
For the Y-Intercept:

Therefore: Y-Intercept is
let's see the graph:
