Understanding Quadratic Functions with No Zeros or Real Roots

This video discusses the limitations of using zeros to graph a quadratic function and introduces the concept of functions with no zeros or real roots. It explains that if a quadratic function has no real number values that make it equal to zero, then its graph will not cross the x-axis. The video also mentions that not all unfactorable polynomials have no zeros, and it hints at the exploration of other techniques to deal with such quadratics.
