The 0’s of a function (x-intercepts) and the signs around those points tell us a lot about what the function looks like. This lesson works through 3 examples covering the zero product rule, multiplicities, and end behavior. Po-Shen Loh teaches not only the skills needed for a foundation in higher math, but also the intuition behind why these concepts make sense so you’ll never forget them!
