5-136.
Start by solving for x.
y = log3x
x = 3y
Now 'rename the x and y'.
f −1(x) = 3x
Notice that y = π² is a horizontal line. What is the inverse of a horizontal line?
y = 62x
2x = log6y
f −1(x) = ____________
Refer to hint in part (b).
Before you convert to a logarithm, subtract k from both sides.
