Step-by-step explanation:
A function can have only one output for any given input. Thus for the repeated input, the function will have the same output repeated.
A non-function will have two (or more) different outputs for one input. So, for the repeated input, the non-function will have different outputs. (Anything that is not 6 will do.)

Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.
The distances:
- from perihelion to the sun in terms of ellipse is a-c;
- from aphelion to the sun in terms of ellipse is a+c.
Then
Add these two equations:
and subtract first equation from the second:
Note that thus
The equation for the planet's orbit is
