what is the range of this exponential function?1) all real numbers 2) { y | y > 0 }3) { y | y ≥ 0 }4) { y | y ≤ 0 }5) { y | y < 0 }

Remember that
The range is the data set of all possible values of y
In this function
y>0
the range is the interval (0, infinite)
therefore
answer is the second option
