Question 6575: I am looking for the inverse of the function y= 3x -1, where x is the power. So it is read, y equal to 3 to the power of x -1. I know the inverse should be in logarithmic form, but I'm not sure whether I log an entire side or not. Then I am suppose to graph the inverse, stating domain and range.
Can you help me?
Thanks.

y=3%5E%28x-1%29, is that what you mean?
y=3%5E%28x-1%29 is equivalent to saying log%28+3%2C+y+%29+=+x-1. That's a trivial equation for x, x=log%28+3%2C+y%29+%2B+1
