Your use of "partly" is not understood. If your teachers uses this term, I suggest drop the class, you are headed for more made up math that is not understood by many math users.

However, in the interests of passing this class, "varies partly" means
x = ay + by^2
Now plug in your points to find a and b:
4a + 16b = 52.8
5a + 25b = 81
Then use your function to find x(6)
