Evaluating a function: Evaluate the difference between f(x) = x^2 - 9x + 5 when (f(x + Δx) - f(x))/(Δx) is calculated. Which of the following options is correct?
A) (x^2 - 9x + 5)/(Δx)
B) (x^2 - 9x + 5)/(x + Δx)
C) (Δx^2 - 9Δx + 5)/(Δx)
D) (x^2 - 9x + 5)/(x)
Note: I removed unnecessary spaces and words to make the question more concise.
