This is a quadratic function because there is a constant second difference.
recursive: f(1)=-3
f(n)=f(n-1)+2n-1
explicit:n^2 -4

I know this is exponential because every value increases times 2 every time.
recursive: f(1)=2
f(n)=f(n-1)x2
explicit: f(n)=2^n

This is a linear function because there is a constant first difference
Recursive: f(1)=2
f(n)=f(n-1)+2
Explicit: y=2x
