Domain: (-3, positive infinity) Range: (0, positive infinity)
Work Step by Step
Domain: The domain is all the possible x-values for a function. Once you have graphed the function, it is learned that the lowest x-value is -3 (because anything lower would lead to a negative within the radical, ex. $\sqrt -1$). Because the function goes on endlessly, the limit is positive infinity. Range: The range is all the possible y-values for a function once you have graphed the function, it is learned that the lowest y-value is 0, and because there is no end to the function, the limit is positive infinity.
