what's the difference of domain of a quadratic function & range of a quadratic function?
The domain of any function are all values of 'x' it is allowed to take on. Likewise, the range of any function are the resulting 'y' values.
|dw:1356772925912:dw| Here the domain is any value x can be. Which in this case is every real number. The range, however, is restricted. Notice that y can only be positive.
