Math 119 - PreCalculus
Final Exam Information
Three hour, cumulative exam, self-scheduled in the finals week (December 14-December 19)
See http://www.randolphcollege.edu/x13440.xml for procedures about self-scheduled exams.
The final exam is cumulative with about 60% from the material covered after the third exam (from section 4.7 to section 6.5) and 40% from earlier material .
Topics
Numbers
The number line
Absolute values
Solving inequalities and sketching them on the real line

Absolute value function, greatest integer function
Polynomial functions (end behavior of a polynomial, rational zeros of a polynomial)
Rational functions
Functions involving radicals
Trigonometric functions
The unit circle and sine and cosine of basic angles (0, 30,45,60, and 90 degrees)
Other trigonometric functions and their relation to sine and cosine
Period and amplitude of a trigonometric function

Right-triangle trigonometry, law of sines, law of cosines
Inverse trigonometric functions
Solving trigonometric equations
Exponential functions
Logarithm functions
Composition of functions

Graphs of circles, ellipses, parabolas, hyperbolas
Using
basic graphs to obtain graphs of more complicated functions
Shift up/down, left/right, stretch
(elongate), compress (shrink) horizontally/ vertically, flip over the
x-axis, over the y-axis
Graph of a reciprocal function
Graph of a rational function
Graphs of inverse functions (mirror image about the line y=x)
Graphs of absolute value functions and step functions (the greatest integer function)
Sketching the graph of a function
Finding the domain
Finding the x,y intercepts
Finding the vertical, horizontal asymptotes
Making a sign chart for the function
Putting all the information together
Applications of functions
Problems involving scenarios from real life - finding the maximum, minimum, problems involving trigonometric functions, problems about compound interest
Practice Problems
Solving ONLY these problems is NOT sufficient to do well in the exam! You should also go over class notes, examples in class, previous quizzes, exams, and homework problems. Pay extra attention to the problems that you had difficulty solving. Learn and understand how to solve them.
