Question

please help me find the intercepts and test for symmetry for : y=(-9x/x^2+9)

Answer 1

y-int are found by setting x to zero and x-int are found by setting y to zero

Answer 2

yes but its in a form that is in a fraction and I am confused

Answer 3

I can probably figure it out if its written like 4x^2+25y^2=100, but its written differently

Answer 4

You would multiply the bottom out when setting y to zero, so you would have -9x=0 which means that when y is 0, then x doesn't exist, so you have a asymptote at that point.

Answer 5

ohhhh thanks , I am not fully understanding this one

Answer 6

Wait is the 9 in the denominator or numerator? I was assuming 9 was not in the numerator.

Answer 7

in the numerator

Answer 8

wait there is a 9 in the numerator and denomiator
