Comparing Function Outputs

Consider the function $$f(x)$$ defined by the equation:

$$f(x) = x^3 - 6x^2 + 9x - 4$$

We want to determine the value of $$f(3)$$ and compare it with the value of the expression $$g(x) = x - 1$$ evaluated at the same point. Specifically, let Quantity A be $$f(3)$$ and Quantity B be $$g(3)$$. What is the relationship between Quantity A and Quantity B?
