Translation of y=x^2

Explanation:

When a quadratic is in the form y=(x-p)^2+q such as this, the negative of p tells us the x coordinate of the vertex of the graph and q tells us the y coordinate.

ie vertex is (-p, q)

Consider the graph y=x^2 and you will notice that it has shifted (translation) 9 units to the right -(-9) and 5 units up. We often write this in column vector form:

((9),(5))
