FIND THE INVERSE:

f(x) = 10^(5x+3) - 10

f^-1(x) =

  • LOGS (ALGEBRA) -

    y = 10^(5x+3) - 10
    (y+10) = 10^(5x+3)
    log(y+10) = 5x+3
    x = (log(y+10)-3)/5

    so, f^-1(x) = (log(x+10)-3)/5

    If f(x)=x^5-1/3, find f^-1(-31/96). I think the first step would be to find the inverse of -31/96, but I am not sure how to find that :). Then I could make x^5-1/3= the inverse of -31/96.
