Slope of inverse? Check

  1. Dec 17, 2004 #1
    :smile: My question says f(x)=(-5/7)x-3 determine the slope of f^-1(x) without finding the inverse. I think the answer is the slope of f^-1(x)=(-7/5)x
    Is this correct?

    Yes. It is correct. Once again, you can check this by graphing the function and seeing the reflection over f(x) = x

    I actually had the same question, where did the -3 go?

    MaryB, the -3 has nothing to do with the slope.
