This week we are learning about vertex form of quadratic equations. Vertex form is y=a(x-h)^2+k. It's called vertex form because the vertex of the parabola is at the point (h,k). a is what's called the stretch factor--it caused the graph to stretch or compress--meaning it's growing faster or slower. So, when graphing quadratic equations in vertex form (Tuesday's assignment), here is what I recommend: drag the vertex to the correct coordinates, then plug in a value for x to find the corresponding y value and then drag the second point on the graph to those coordinates. Next (Wednesday) you have some application problems (word problems) that are similar to the ones you did before, only this time the equations are in vertex form rather than factored form.
Thursday and Friday: review solve by factoring. First you will factor each equation (write the sum as a product), then use Zero Product Property to find the solutions. Remember to factor out the GCF if an equation has one.
