Question 1049849
I have a problem here on my college algebra homework. It's x= square root of y. Need domain & range, how to graph it & determine if it's a function. 
<pre>{{{x = sqrt(y)}}}
Domain: {{{highlight_green(matrix(1,2, ALL, REALS))}}}
Range: {{{highlight_green(matrix(1,3, ALL, REALS, "">= 0))}}}
