How do you find the domain and range of #-x^2+7#?
Finding the Domain
The domain is where the function is defined in terms of real numbers. This function is always defined, so the domain is all real numbers,
Finding the Range
The range is the possible values that the function takes on. If we consider the function as a parabola, we can see that it will be concave downwards (
This means that the range will be
