No, it’s not really a parabola. After we admired it briefly, and talked about why it didn't meet the definition of a quadratic function, someone realized that we could turn the graph into a parabola if we just changed the exponent on from a 3 to a 1. I'm hopeful that having come to this insight this way will help students to see and more easily remember how they can go from the standard form of a quadratic equation to its graph without having to complete the square and without relying on having memorized that the x-coordinate of the vertex is (and students who think about this form of a quadratic equation carefully, can finally see why must be the x-coordinate of the vertex.). I added on the fun activity towards the end, where the students can try to match the pictures. Key vocabulary that may appear in student questions includes: degree, roots, end behavior, limit, quadrant, axis, increasing, decreasing, maximum, minimum, extrema, concave up, and concave down.
