I dont know how to write these functions in Graph

y= 3x/(x+2)^2

y=√x - 5x

You'll find your functions in pict. 1.

Please note that only real results are shown for the second function. Complex solution for any value x<0 can be found in Evaluate dialogue (Ctrl-E).

The equation "y=√x - 5x" returns real solutions for x>=0, and complex solutions for x<0:

y= - 5x + i*sqrt(-x) ;

In picture 2 results in complex plane are shown, with x values advancing in 0.1 steps, just for better imagination.

thank you
