Comparing Linear and Quadratic Functions

1. y=f(x)=a+bx

2. Straight line when graphed

3. Independent Variable = x

4. Dependent Variable = x

5. Linear Functions

6. Quadratic Functions

7. f(x)=ax^2+bx+c

8. When graphed, they end up being curved in a "U" shape.

9. "U" shape could open upward or downward.

10. A is positive= opens upward                  A is negative= opens downward
