Week 8

This week in Pre Calculus I learned how to find the vertex of a quadratic formula if the equation is in standard form. Standard form looks like:

The x and y variables can represent any point besides the vertex on a graph. The p represents the x value of the vertex and the q represents the y value of the vertex. If the equation was:

The -7 is the x value in the vertex and the -1 is the y value in the vertex, the vertex of this equation would be (7,-1). There could be some confusion that the vertex should be (-7,-1) but this is not the case. The sign in ONLY the x value gets flipped essentially making it a positive in this case. This is what the parabola would look like on a graph:
