Which point of reference is equation y = x5 symmetric about

A. x-axis

B. y-axis

C. origin

D. It is not symmetric about any line or point.

E. It is symmetric about the x-axis, y-axis, and origin.

Hi,
I assume you mean x^5. Since this is an odd function, it is symmetric about the origin. Remember that for an odd function f(-x) = -f(x) for all x in the domain of f.

you really need to plot this one to see the symmetry
