What is the range of the function? (put answer in interval notation)

Question

Find the range of the function. (Enter your answer using interval notation.)

function: h(x,y) = x√y

Answer 1

the range is all reals

if x and y are both positive, the result is positive

if x is negative and y is positive, the result is negative

If either x or y is zero , the result is zero.

here are the limits : x across columns, y along the rows

-infinity zero infinity

==========================================

zero zero zero zero

infinity -infinity zero infinity
