How do I do FFT for small amount of points?

I have a small amount of data points X=[8 7 2 4 5 1] that I want to perform FFT for in order to find the trig functions that compose this repeating pattern. Is there an easy way to code this? I've seen a bunch of code that works for continuous samples of waves but I want to downsize it.

See the first example in the fft documentation as that shows how to label the x axis with frequency
