(see below)

Explanation:

It is unclear what you are looking for here (especially since this appears under "Rotations of a Conic Section").

The X-axis is the collection of points for which $y = 0$ $y=0$ .
If you are looking for the x-intercept, it is
$XXX (ˆ x, 0)$ $color(white)("XXX")(hat(x),0)$ where $f (ˆ x) = 0$ $f(hat(x))=0$
$XXX$ $color(white)("XXX")$ i.e. you need to solve your function for when the function equals zero.

The Y-axis is the collection of points for which $x = 0$ $x=0$
If you are looking for the y-intercept, it is
$XXX (0, f (0))$ $color(white)("XXX")(0,f(0))$
