2.7 Applications of Rational Equations
The last section of unit 2 will be applications/ word problems. Although they may seem intimidating at first, once you learn the different methods of solving them, it will be much easier! Strategies for Solving Word Problems Read the problem carefully, many time. Know what you need to solve for, and what you are given.…
2.6 Graphing Rational Functions
Do you guys remember how to graph a function? Back in Math 10, we graphed different linear equations such as lines, slopes etc… It’s finally time to graph a rational function! How exciting! But first, what is a rational function? A rational function is f(x) = g(x)/ h(x), where g(x) and h(x) are both polynomials.…
