To rewrite the function f(x) = 0.125x^3 in the form f(x) = a(1+r)^x, we need to find the values of a and r.
First, let's write 0.125 as a fraction: 0.125 = 1/8
Now we have f(x) = (1/8)x^3, which can be rewritten as f(x) = (1/8)(1+r)^x.
Comparing the two forms, we can see that a = 1/8 and (1+r) = x.
So, a = 1/8 and r = x - 1.
