Parabola Day!

We started our review of quadratics today and also introduced the concept and notation for domain and range.

We looked at the visual pattern, modelled it with a function, made a table of values and a graph. We used our prior knowledge to determine the vertex (by factoring, quadratic formula, or knowing that the axis of symmetry is x=(-b)/(2a)). Once the axis of symmetry is found we sub that in as f and calculate the y value of the vertex. The range is going to be based on this value.

I was really proud of how students are helping others, and how many different strategies they are using.
