Evaluate the diference quotent

  1. Jul 23, 2009 #1
    Evaluate the difference quotient for the given function, simplify your awnser

    f(x)=(x+3)/(x+1)

    f(x)-f(1)/(x-1)

    HELP PLEASE

    Do you know what the difference quotient is? If so, list it please. Also, I'm not for sure what you mean by f(x)-f(1)/(x-1). Is there a typo here?

    Note that "f(x)- f(1)/(x-1)" means
    [math]f(x)- \frac{f(1)}{x- 1}[/math]

    Did you mean
    [math]\frac{f(x)- f(1)}{x- 1}}[/math]?

    If so, please show what you have done. What is f(1)? What is f(x)- f(1)?

    f(x)-f(1)/(x-1) = (x+3)/(x+1) - (1+3)/(1+1)/(x-1)
