ALL WORK IS TO BE COMPLETED ON SEPARATE PAPER. IT IS EXPECTED THAT YOUR WORK
WILL REPRESENT COMPLETE, NEAT AND ORGANIZED SOLUTIONS TO THE STATED PROBLEMS
1. Write an equation of the line through the point 8,3 and parallel to the line given by
2x 3 y 5 .
2. Find the x and y intercepts of the following equations:
a) y x 2 6
b) y x 4 1
3. Given the following pairs of functions, determine the requested domains:
Df g ,

4. Find a polynomial function with integer coefficients whose zeros are: 0, -1, 2 3 .
5. Solve the inequality, sketch the solution on a number line, and present the solution in
interval notation.

6. Find the quadratic function that has 4, 4 as the vertex and whose graph passes
through the point 5,9 .
7. Determine algebraically any points of intersection of the graphs for the following
equations.
y 9 x 2 and y x 3
8. Find the inverse of the function of y x 4 including proper domain considerations
and then verify that it is the inverse via proper algebraic composition with the original
function.

transformations of f . NOTE: Each sketch, a through e, must be presented on a
separate coordinate plane (no “combo” graphs).
