There are an infinite # of them.
The other tutor showed a parabola.
A circle can be found, and an infinite # of ellipses.

Continuing the response from tutor @alan3354, there are also an infinite number of polynomial equations that are satisfied by the three given data points.
However, since the value is cut in half for each increase of 1 in the x value, an exponential function would seem the most appropriate: .
The constant factor in the given sequence is 1/2 or 0.5:
When x is 0, y is 38:
So the exponential function for the given points is
