Question

how to find the inverse function of 3x+lnx

Answer 1

then find f-1(3)

Answer 2

to take inverse of this question you need to combine the expression such that you get a new function. in form
f=ln(something)

Answer 3

and how would you do that?

Answer 4

ok check this out:
3x=ln(e^(3x))

Answer 5

totally lost, don't know how you got it

Answer 6

y=3x+lnx
x= 3y+lny
x=y(3+ln)
y= x/ 3+ln
not sure

Answer 7

ok see you know this form of ln function:
ln(e)=1
ln(e^5)=5ln(e)

Answer 8

5ln(e)=5

Answer 9

non nancy that's not possible
you cannot take y common like that

Answer 10

nope, sorry, still doesn't make sense
