I'm stuck, what would be two inputs for this nonlinear equation?
f(x) = x³  7 x = 2 x = 2

Reiny,
The reason you have received no reply so far is because the way you typed your function is confusing.
You have 3 equal signs in the same line, is that what you wanted?
is your function f(x) = x^{3} ?
if you simply want f(2) and f(2) that would be easy
f(2) = (2)^3  7(2)
= 6
f(2) = 2^3  7(2)
= 6
