The following function is one to one. Find the inverse. Find the domain and range of f and f^-1 f(x)=8x-8
You need to write the function such that: `y = 8x - 8` .
You need to write the function in terms of x to find its inverse such that:
`8x = y + 8 =gt x = (y+8)/8`
Hence, the inverse to function f(x) is `f^(-1)(x) = (x+8)/8` .
Since the equation of the inverse function holds for each real value of x, hence the domain of inverse function is the real set R and the range is also R.
Hence, the real set R stands for domain and the range of the inverse function `f^(-1)(x)=(x+8)/8` .
