Inverse of y=...?

1 answer

I need to find the inverse of y=log2(x-3). The 2 after the log is subscript. I got y=2x+3 did I do it right? Steps: Switched x and y and then 2x=y-3

    y = log(base 2)(x - 3) Change y to y^-1, swap y^-1 and x, and solve for y^-1. x = log(base 2)(y^-1 - 3) 2^x = y^-1 - 3 2^x + 3 = y^-1
