When solving an equation for a given variable *such as solving for x*, how can you prove if the answer is correct?

### Subject:Algebra

Question:

Describe the difference between Linear, Exponential and Quadratic functions, and provide an example of each.

Molly W.

Linear functions have a constant rate of change, and therefore create a straight line when graphed. An example would be anything in the form y=mx+b. Exponential functions have a constant multiplier, and therefore when graphed will increase or decrease rapidly in the form of a sharp curve. An example would be anything in the form y=a*b^x Quadratic functions have a common second difference, and therefore create a "u" shape when graphed. An example would be anything in the form y=ax^2+bx+c.
