Comparing Linear && Quadratic Functions
by Grant Scott-Colvin
1. Quadratic:
2. f(x) = ax2 + bx + c
3. curve called a parabola.
4. parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape.
5. Linear:
6. Straight Line
7. y = f(x) = a + bx
8. Dependent Variable = y, then independent = x
