SOLUTION: If {{{ r(x)= sqrt(x+1)-2 }}}; find A. r(x)<0 B. r(x)>0 I'm completely lot. I plugged in random values for x to get y. Like this: When x=8; y=1 I'm not sure what to do

Question 1073578: If ; find
A. r(x)<0
B. r(x)>0
I'm completely lot. I plugged in random values for x to get y. Like this:
When x=8; y=1
I'm not sure what to do from there...
Thank you so much!!!!
