OBJECTIVES: Upon completion of Math 108, the student should be able to
- Set up algebraic models (equations or inequalities) for various phenomena, solve, and eliminate
solutions which are invalid in the context (including but not limited to linear models.)
- Solve inequalities involving absolute value, represent their solutions as intervals, and graph the
solutions.
- Perform algebraic operations on polynomial and rational functions, and factor polynomials (as a
tool for solving polynomial and rational equations, not an end in itself.)
- Use polynomial long division as necessary to simplify expressions. (Synthetic division is optional.)
- Solve algebraic equations and inequalities, including expressions involving radicals.
- Determine intervals where polynomial and rational functions are positive and negative.
- Understand the relationship between zeros and linear factors of a polynomial; use the rational root
theorem.
- Demonstrate understanding of the function concept and the related concepts of domain and range.
- Quickly recall and sketch the graphs of the functions f(x) = x2, f(x) = x3, f(x) = 1/x, f(x) = 1/x2, f(x)
= |x|, f(x) = x1/2, f(x) = x1/3, etc.
- Recognize and use symmetry in graphing equations.
- Recognize and use the effects of shifts, reflections and scaling on a graph.
- Graph polynomial and rational functions showing intercepts and horizontal and vertical
asymptotes.
- Compute the composition of two functions; recognize a given function as a composition of other
functions.
- Demonstrate an understanding of the concepts of one-to-one functions and inverse of a function.
- Compute the inverse of a function and its domain and range; sketch the graph of the inverse of a
given function.
- Quickly recall and sketch the graphs of basic exponential and logarithmic functions.
- Solve exponential equations using one-to-one property of exponential functions and /or using
logarithms.
- Use the laws of logarithms to simplify logarithmic expressions and to solve logarithmic equations.
- Convert equations from logarithmic to exponential form and vice versa.
- Find the key features of a parabola or circle given its equation.
- Derive the equation of a parabola or circle given its key features or a graph.
