In this lecture we dissected the terms that make up a quadratic equation, and looked at how each of these components affect the shape and position of the curve.
Did you expect each term to affect the curve in the way that it does?
Just wanted yāall to know itās great stuff and Iāve enjoyed the course. Shame itāll hit an end so soon but easy to binge through.
@XavierMagnus Iām glad to hear that youāre enjoying the course, and great work making it through all of the current content.
The next section on āAngles and Circlesā will start very soon (within days). And weāll be adding around 2-4 new lectures a week that section. We also have additional sections planned after that, so the course isnāt quite finished yet!

This was fun and it surprised me, but understandable.
If a is ā0ā, no parabolic line, but a horizontal line. As explained.
Changing b, the straight line rotated. Due to b acting as the line gradient.
And the increasing b sets the line in a more vertical position.
But, as we learned in previous lessons. There can not be a total vertical line.
The higher b, the less influence is has on the nearly verticalness? of the line.
This weblink, for the graph, made things clearer. THX

Did anyone else spend way too much time on the Exploring Quadratics pageā¦?
Because I did haha! Learning CAN indeed be fun.
Cheers
Wow a tool I can use, now go back to the other lessons and try to get my head around it
