 When posting here in the Weekly Summary section please do not post "answers only" but rather show how you obtained your answers in a step by step manner. If your solution is correct, it is in your best interest for us to see how you obtained the answer. If your solution is incorrect, showing your steps will help us to follow your process and we can then work together to find your mistake. No bonus points will be awarded for answers without explanations. At least 5 correct answers.

1. If f(x) = 4x2 - 3x + 2, evaluate f(-1).
2. State the domain of the function f(x) = (x+3)/(x-1).
3. Write the equation of the line that passes through the points (1, 1) and (2, 4).  Write your answer in slope-intercept form.
4. Write the equation of the line with a slope of 2/3 and y-intercept of 1.  Write your answer in slope-intercept form.
5. Solve the equation:  (4x+1)(2x-7) =0.
6. If f(x) = 4x + 3, evaluate f(x+h).
7. If g(x) = x², evaluate g(x+h).
8. If f(x) = -x + 1, evaluate f(x+h).
9. If f(x) = -x + 1, evaluate f(x-h).
10. Use the quadratic formula to solve the equation:  x² - x - 1 = 0.
