Question

the graph of a square root function has a domain of (0, infinify ) and range of [1, infinity) explain how the given range of the function can help you to the maximum of minimum y-value of the function? HELP

Answer 1

The range is [minimum y-value, maximum y-value), so the range expression tells you directly what those values are.

For the function described, with range [1, ∞), ...

... minimum y-value = 1

... maximum y-value = infinity
