COURSE
DESCRIPTION:
This course provides an
integrated approach to technology and the skills required to manipulate,
display, and interpret mathematical functions and formulas used in problem
solving. Topics include simplification, evaluation, and solving of algebraic
and radical, functions; systems of equations; complex numbers; right triangle
trigonometry; systems of operations, and the use of technology. Upon completion,
students should be able to demonstrate an understanding of the use of
mathematics and technology to solve problems and analyze and communicate
results.

arithmetic operations with polynomials and algebraic fractions.
2)
Simplify
complex fractions.
3)
Simplify and
evaluate powers having rational exponents.
4)

and translation to sketch the graphs of given functions.
15)
Given
functions f and g, find f + g, f - g, f . g,
f/g, f -1, and fog.
16)
Graph
exponential and logarithmic functions.
17)
Evaluate logb(x) for allowable values of b and x.
18)

exponential and logarithmic equations.
20)
Solve word
problems which can be modeled by an exponential or logarithmic function.
21)
Solve a system
of two equations in two unknowns.
22)

COURSE
AVERAGE: 10% homework and/or pop quiz average
75%
major test average
15% comprehensive
final examination.
A student who has two or fewer absences may drop
the lowest of the pop quiz grades in determining the pop quiz average. A student who has more than two absences, may not drop any pop quiz
grade. No distinction is made between excused and
unexcused absences. (Being tardy is an unexcused absence.)
