The graph of the cosine function f( )=cos( ) has many properties. Amplitude of this cosine
function is 1. It has a maximum value of 1 and minimum value of -1. The amplitude is equal to
the radius of the unit circle. The cosine function is a periodic

Description of the Examination
The Precalculus examination assesses student
mastery of skills and concepts required for success
in a rstsemester calculus course. A large portion
of the exam is devoted to testing a students
understanding of f
1. Graph the function
and answer the following questions:
Determine the interval(s) where the function f(x) is increasing? is decreasing?
Determine the relative minimum and maximum values of the function.
Determine all the intercepts.
Determine whether f(
1. Exponents
When we multiply numbers together, each of the numbers is called a factor. In the special situation where some
of the numbers are the same, we use exponent notation. When we use the form a" , the n is called the
11
exponent and the a is

(Corresponds to Precalculus Competency - Preparedness for M151)
The Test 2 Placement exam is a multiple choice exam covering topics typically found in a Precalculus
course. Passing the exam means
3. Factoring
Ifwe want to write an expanded expression in factored form we un-multipbz. Always check factoring by
remultiplying.
Removing a common factor

Example 1: E x y + E xy = g xy(x + 2) Ch
2. Multiplying
We use the distributive property combined with the rules of exponents to nd products where one of the factors is a
sum of terms.
