Find the domain and range y=x^2-3x+8. Explain how you found the domain and range.

Answer 1

The domain of x is not restricted, it is all real numbers. -inf<x<inf
That is true because any real number of x will yield a solution.

the range of y is from the minimum to inf. The minimum y occurs when x=3/2, and y for that is ...you figure it.
