1. Review 2-1 and 2-2

2. Quiz Overview (non-calculator) 2-1a) graph power functions (4 points, 8 matching) b) solve radical equations (4 points, 2 equations) 2-2 graph polynomials by finding zeros, y- intercepts, end behavior, and multiple roots – may require factoring (6 points, 2 graphs) 2-3a) use long and synthetic division - with factoring (5 pts) b) use direct and synthetic substitution - remainder theorem (2 pts)

3. Solve. 1. √(4-3x) = 5 x = -7 2. 3 √(x 2 – 1) = 2 x = ±3 3. (15-x) 3/2 = 27 x = 6 4. x – 2 = √x x = 4 (x = 1 does not check) 5. 2x = √(28x + 29) – 3 x = -1 or x = 5 6. √(x-3) + √(x+4) = 7 x = 12

4. Graph. Find the zeros and y-intercept. Check for end behavior. You should check on calculator. 1. y = x 4 + x 3 – 12x 2 2. y = -2x 3 – 4x 2 + 18x + 36 3. y = -2(x-2) 3 (2x+7)

5. Sketch each of the graphs using your knowledge of domain and end behavior. Check on your calculator 1. y = 3x 4 2. y = -2x 7 3. y = 7x -2 4. y = 2x -3 5. y = x 3/4 6. y = x 5/4 7. y = x 1/3 8. y = x 2/3

6. Review 2-3 on your own from notes/homework.
