Advanced Algebra Module 05 Problem Set

1. Graph f(x) = -2x – 3

2. Use the quotient property to rewrite log10( ).

3. Find the x-intercept and the y-intercept of -3x + 5y = 30. Show your work.

4. Match the function in the 1st column to the Domain in the 2nd column.

FUNCTION (A-D)	Domain (a-d)
A. { (-2, 7), (3, 0), (0, -4), (5, -5)}	a. Real Numbers such that -3 < x < 3
B. f(x) = 4-3x	b. Domain is all Real Numbers except x = 4.
C. = y	c. Range ( -2, 3, 0, 5)
D. f(x) =	d. Domain is all Real Numbers

5. (g o f)(x) means g(f(x))

Find ( g o f)(3) if f(x) = -4x + 2 and g(x) = . Show your steps/work.

6. Rationalize the denominator:
