Part 1
Setting the Foundation: The Nuts and Bolts of Pre-Calculus
IN THIS PART …
Pre-calculus is really just another stop on the road to calculus. The chapters in this part begin with a review of the basics: using the order of operations, solving and graphing equations and inequalities, and using the distance and midpoint formulas. Some new material pops up in the form of interval notation, so be sure and check that out. As you move on to real numbers you find yourself focusing on radicals. Everything you ever wanted to know about functions is covered here: graphing and transforming parent graphs, dealing with rational functions, and piecewise functions. You'll see how to perform operations on functions and how to find the inverse. Then you move on to solving higher-degree polynomials using techniques like factoring, completing the square, and the quadratic formula. You also find out how to graph these complicated polynomials. Lastly, you discover exponential and logarithmic functions and what you’re expected to know about them.
