y = 6^(x-5) , switch x and y
x=6^(y-5) , now solve for y
OpenStudy (anonymous):
your inverse is x = 6^(y-5)
OpenStudy (anonymous):
my teacher answer is f-1(x)=5+log6x i dont know how she got it
OpenStudy (anonymous):
solve for y satan
OpenStudy (anonymous):
satan?

yes?
OpenStudy (anonymous):
i am a satan worshipper
OpenStudy (anonymous):
interesting but im not sure how to solve for y
can you walk me through
OpenStudy (anonymous):
i just prayed for satan's help
OpenStudy (anonymous):
ok one sec

take that kind of talk somewhere else, you may be playing but we are here to solve math problems
OpenStudy (anonymous):
^^what lagrange said but i dont judge
OpenStudy (anonymous):
hey, dont persecute my religion
OpenStudy (anonymous):
ok x = 6^(y-5)
OpenStudy (anonymous):
take log base 6 of both sides

can you demonstrate how you were earlier with the numbers
OpenStudy (anonymous):
satan ish baladdama
log_6 (x) = log_6 ( 6^(y-5)
OpenStudy (anonymous):
first i switched x and y
OpenStudy (anonymous):
yea so x= 6^y-5 right?
OpenStudy (anonymous):
yes, now take log base 6 of both sides

that will cause the right side to cancel
OpenStudy (anonymous):
log6x= log6y-5?
OpenStudy (anonymous):
is that what you mean by take log 6 of both sides?
OpenStudy (anonymous):
you have to be more careful
OpenStudy (anonymous):
log_6 (x) = log_6 [ 6^(y-5)]

OpenStudy (anonymous):
but you have the right idea ;)
OpenStudy (anonymous):
o ok
OpenStudy (anonymous):
the right side should cancel
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
so after the right side cancels we are left with
log_6 (x) = log_6 [ 6^(y-5)]
log_6 (x) = (y-5)

ok what do you do next
OpenStudy (anonymous):
now add 5 to both sides
OpenStudy (anonymous):
log_6 (x) = log_6 [ 6^(y-5)]
log_6 (x) = (y-5)
log_6 (x) = log_6 [ 6^(y-5)]
log_6 (x)+5 = y
OpenStudy (anonymous):
log_6 (x) = log_6 [ 6^(y-5)]
log_6 (x) = (y-5)
log_6 (x)+5 = y
