Question 994548: For the equation 9 x ^3 - 9 y ^2 = -6 answer the following questions.
Is the equation symmetric with respect to the y-axis? ( yes or no)
Is the equation symmetric with respect to the x-axis? ( yes or no)
Is the equation symmetric with respect to the origin? ( yes or no)
I have substitute both axis and the origin with the corresponding transformation of -x and -y. However, I couldn't find the right answer and I would like to know what I did wrong.
For example,
x axis: 9x^3-9(-y)^2=-6
9x^3-9y^2=-6 <-- same equation as original therefore Yes
Y axis: 9(-x)^3-9y^2=-6
-9x^3-9y^2=-6 <--- not the same equation as original therefore No
Origin: 9(-x)^3-9(-y)^2=-6
-9x^3-9y^2=-6 <--- not the same equation as original therefore No
