Curve Tracing

[Liam22]

greetings everyone, were currently studying curve tracing in analytic geometry. i always get stucked in a problem when the left side is ^2
[i.e. y^2 = (6+5x+x^2) / (x-4) ] so to get the y we'll have to change the values of x to 0. then i i dont know what do to next with the y^2, if ill just leave it or not. i hope somebody could teach me how to get the answer in this. thanks in advance.

You understand that, in a graph, you are using x and y, not \(\displaystyle y^2\), don't you? Once you have calculated \(\displaystyle y^2\), take the square root to find y. And, of course, if \(\displaystyle y^2= a\) then \(\displaystyle y= \sqrt{a}\) and \(\displaystyle y= -\sqrt{a}\).

thanks for the reply.
