10. When asked for average slopes on each of three intervals, this means give three slopes, each being the average for one of the intervals. It doesn't mean average the three slopes.
9. Explain the meaning of the slope by first explaining the meaning of the rise and the meaning of the run
8. The vertex has two coordinates. You aren't done when you've found -b / (2a)
7. Know the slope = slope picture, with specific points (x1, y1), (x2, y2) and general point (x, y) and how to use it.
6. m is the slope and b is the y intercept of a linear function; if m varies then slope varies; if b varies then the y intercept varies.
5. Use proportionality correctly. Know the lesson of mama whale and baby whale. Know how squares scale up and how cubes scale up.
4. P = P0 b^t, where P0 is the t = 0 quantity and b is the growth factor
3. 5 percent is .05, a typical growth rate, and you add 5 percent by multiplying by 1.05, which is the corresponding growth factor
2. If you are given the value of f(t) substitute it for y, not for t.
1. Use basic point scheme to graph. You never need more than 3 points except for power functions, where you need 5.
