Quadratic Functions VS. Linear Functions

1. Quadratic Functions

1.1. f(x) = ax2 + bx + c

1.2. The graph of a quadratic function is a curve called a parabola

1.3. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape.

2. Linear Functions

2.1. F(x): a=bx

2.2. Made of one independent and one dependent variable.

2.3. Graph is a straight line
