through out this past semester of pre calc 11 I’ve learned a lot of new ways of math, the one I would like to show you that has now stuck with me is how to determine non-permissible values from rational expressions.

In this question, you first start by taking out the denominator. With this denominator factor it to find the x values. The denominator can never equal zero. By finding finding the x’s you are finding the non-permissible values.
