For the function f(x) = x^2 - x, what is (f(3) - f(2))/(3 - 2).

The function f(x) is defined as y = f(x) = x^2 - x.
The slope of a line joining two points `(x_1, y_1)` and `(x_2, y_2)` is given by `(y_2 - y_1)/(x_2 - x_1)` .
The expression `(f(3) - f(2))/(3 - 2)` is the slope of the line joining the point where x = 3 and the point where x = 2.
