Finding Zeros of a Function

The zeroes of functions is where the graph crosses x. To find zeroes of a function you set the equation equal to zero. Another way to do/say this is to set y equal to zero. Once you do this simply solve the equation for x. Some times you will get more than one answer and that's okay. When you get the same number multiple times that number has multiplicity. For example if you get the number two three times you would say 2 has a multiplicity of three and if 5 appeared seven times you would say five has a multiplicity of seven. Here is an example of finding zeroes.
