Barry UniversityMAT 109 - Precalculus Mathematics IMAT 109 Final Exam Study GuidenthSemesterWriter: ”Lew” Sterling Jr.Objective:The objective of this final exam study guide is to prepare yourself forthe upcoming final exam for Precalculus Mathematics I. Take your time when youread each question and what you need to do in order to solve various problems thatyou have learned during the duration of taking Precalculus Mathematics I.General Instructions:Read each question carefully. Show all work to show thatyou understood how to solve each problems correctly. Just remember to take yourtime and for some problems, there are more than one way to solve some problems(and especially when it comes to establishing the identities).In this final exam study guide for Precalculus Mathematics I, you will have to un-derstand how to do the following things to get ready for the actual final exam of thisrespective mathematics course:•Finding the domain of functions•Finding the intercepts of functions•Finding the (horizontal and vertical) asymptotes of functions•Finding the average rate of change•Finding inverse functions•Finding the difference quotient of functions•Expanding logarithmic expressions•Solving logarithmic and exponential equations•Graphing functions•Solving polynomic and rational inequalities•Convert logarithms into exponential form•Constructing polynomials•Evaluating functions•Solving functions•Finding the zeros of polynomic and rational functions•Function composition•Computing functions using function composition•Finding values of logarithms•Finding the equation of an ellipse•Exponential growth•Dividing and factorizing polynomic expressions•Finding the equation of a parabola
Section A.Find the domain of each function.When it comes to finding the domain of various functions, you have to know what typeof function you are dealing with in order to how to set and find its domain, which meansdoing the following:FunctionDomainConstantDomain =<PolynomialDomain =<RationalSet denominator6= 0RadicalSet inside≥0LogarithmicSet inside>01.f(x) =2x+3x2-5x+6
