Hi, i hadd a problem y= ((8)/(x^3))-((6)/(x))

I need to know hoe the graph is symetric with respect to the

1)x axis

2)y axis

3)origin

I just needed to know the analytical way to find it without looking at the graph

The graph of a function is symmetric with respect to:

- the y-axis if f(x) = f(-x) for all

- the origin if f(x) = -f(-x) for all

If a graph is symmetric to the x-axis it is**not**the graph of a function:

For every x-value you have pairs of y-values such that

To your function:

a) Symmetry to the y-axis:

That means: No symmetry to the y-axis.

b) Symmetry to the origin:

That means: Symmetry to the origin.
