ALGEBRA 2Sec 5.1 GRAPHING QUADRATIC FUNCTIONS
QUADRATIC FUNCTIONS: Different Forms
NOTE: The DISCRIMINANT
In other words, the DISCRIMINANT tells us the type of type of solutions for f(x) = . . . = 0, which tells us the # of xintercepts:

Intercept Form gives you the xintercepts right away
BUT with my special graphing checklist, you were asked to do parts A thru I:
NOTE: In intercept form, you can see the xints here:
