comparing linear and quadratic functions

1. quadratic

1.1. Quadratic function is f(x)=ax^2+bx+c

2. linear

2.1. The independent variable is x and the dependent variable is y , the formula looks like y=f(x)=a+bx

3. linear

3.1. A linear function is a straight line, with one independent and dependent varaible

4. quadratic

4.1. To solve a quadratic formula and getting the x's you half to plug in your a,b,c in to -b+-b^2-4ac all over 2a

5. both

5.1. A quadratic formula graph is a parabola , rather then a line like a linear function, but are both graphs.
