  Topics: • Using the tools of Session 12 to find the domain of a radical function (Exercise 12.3, which was not assigned, but a student did some of it for us.)   • Basic exponential functions and their graphs … Continue reading →

Topics: • Quick review of the first method of solving absolute value inequalities, expanded to also look at the graph. See Example 12.4(d) in the textbook. • Solving linear inequalities: this is just like solving linear equations, except that when … Continue reading →

Please go through the checklist and make sure that you have everything set up. Especially make sure you have an email address in WeBWorK, as that will be used to send out midterm grades later on.

(after Test 2 on Thursday) Topics: Rational Functions and their graphs • Domain: the domain of a rational function will be all real numbers except the x-values which make the denominator 0. • Vertical asymptotes: these occur where the denominator … Continue reading →

Topics: • More on complete graphs of polynomials and recognizing when we do not have a complete graph. Facts about polynomial graphs: • The domain of a polynomial is the whole real line • The y-intercept is the constant term … Continue reading →

Topics: • Synthetic division (a short way to do long division when dividing by x-c) • Roots, factors, and remainders: the Remainder Theorem and the Factor Theorem SUMMARY: For any polynomial f(x), he following three things are equivalent: f(c) = … Continue reading →

The WeBWorK and Warm-Up deadlines from last class have been extended to Monday evening 11 PM.

Topics: • Definition of the inverse function • Finding a formula for the inverse of a one-to-one function algebraically   Important Notes: • For a one-to-one function , the inverse function is denoted by . This is read “f inverse … Continue reading →
