Domain is any real value with x≥−4andx≠0
Range is any real value except 0.

Explanation:

y=√x+4x. for finding domain under root should not be less than zero and denominator should not be zero.
Domain: (x+4)≥0orx≥−4andx≠0

Domain (value of x) is any real value with x≥−4andx≠0
Range (value of y) is any real value except 0. graph{(x+4)^0.5/x [-10, 10, -5, 5]}
