Answer:

y = lnx / ln 7.

Step-by-step explanation:

x = 7^y

Take logarithms of both sides:

ln x = ln 7^y

ln x = y ln 7     ( because ln a^b = b ln a.   One of the Laws of Logarithms).

y = lnx / ln 7.

Which is the inverse of the function f(x)=1/3x+5 ?
PtichkaEL [24]
To find the inverse of a function, switch the x and the y and then solve for the new y.  Like this: x= \frac{1}{3}y+5.  Subtract 5 from both sides to get x-5= \frac{1}{3}y and then multiply both sides by 3.  3(x - 5) = y.  B is your choice.
