Week 8 – Parabolas

this week in math we learnt more about parabolas and I tried relating this week to last week and show you how helpful the discriminant truly is.

here we have 3 parabolas that show the different types of discriminant, in the first one the discriminant is greater than zero and intercepts the x-axis twice meaning we have 2 roots

in the next we have the parabola touch the x-axis which means we have only 1 real root

in the last one the parabola doesn’t even touch the x-axis which means we don’t have an intercept and no roots
