Question 970636: The function f(x)=6x+1 is one to one.
a.) Find the inverse of f.
b.) Graph f, f^-1, and y=x on the same set of axes.

Anyone that can help me...

You can put this solution on YOUR website!
y=6x+1 {y is same as f(x)}
x=6y+1 {to solve inverse, switch x and y, then try to get y}
x-1=6y
(x-1)/6 = y (now, this is the inverse for your question)
to complete your answer, put the negative sign in the exponent LIKE y^-1 or f(x)^-1
a) f(x)^-1 = (x-1)/6
