This week, I learned how to use the table of values in a quadratic formula to find the vertex, x-intercepts, y- intercepts, range, domain, line of symmetry, whether if its maximum or minimum and direction of parabola.
A formulas we could use are 
The vertex of the quadratic is at (p, q) and for the second formula, we know that x can be -b or -c. We could find a by plugging the points.
This method helps us to draw the graph easily.
