**Who must take the test?
**If you plan to take MATH 425 and you have not met the prerequisite,
you must take the placement test. Note that the prerequisite for MATH
425 is a grade of C or better in
MATH 418 (Analysis and Applications of Functions), or placement via the
placement test.

**
What material does the test cover?
**
The test is a 40-question multiple-choice test covering topics from
algebra and precalculus. Calculators are not allowed. Topics include,
but are not limited to, the following:

- algebraic fractions
- exponents, roots and radicals
- logarithms and their properties
- inequalities
- absolute value
- factoring
- solving equations and inequalities, including
- linear equations or inequalities
- systems of linear equations or linear inequalities
- quadratic equations or inequalities
- equations involving radicals
- equations or inequalities involving absolute value

- functions, including
- composition of functions
- domain and range of a function
- transformations of functions
- inverse functions
- logarithmic and exponential functions
- trigonometric functions

- topics from trigonometry, including
- basic trigonometric functions and their transformations
- values of the trigonometric functions at "special" angles
- graphs of trigonometric functions
- basic trigonometric identities
- notions of period, amplitude and phase shift
- inverse trigonometric functions and their graphs

**Are there any review materials available?
**
Online review materials for some topics can be found on the "Math Help
Center" (MaC) webpage.
