    Express in Simplest Form

    Express [f(x + h) - f(x)]/h, where h cannot = 0
    when f(x) = 5

    The answer is 0 but I have no idea how to solve it. Believe it or not, this question comes from a pre-algebra textbook NOT calculus.

    Hi

    Since f(x)=5 (a constant) , so f(x+h)=5 too .

    (5-5)/h=0/h=0

    After playing it with further, I also determined that f(x+h) also = 5.

    Thanks
