Question

How do you get the inverse of this function 3^x

Answer 1

\(y = 3^x\)

solve x

Answer 2

x=3^y

Answer 3

x^3=y

Answer 4

Answer 5

is it write?

Answer 6

you need to take log both sides

Answer 7

\(\large y = 3^x\)

take \(\log_3 \) both sides

\(\large \log_3 y = \log_3 3^x\)

Answer 8

see if u can do the rest

Answer 9

y= log_3/log_3 3^x

f^-1=log_3/log_3 3^x

Answer 10

\(\large y = 3^x\)

take \(\log_3 \) both sides

\(\large \log_3 y = \log_3 3^x\)

\(\large \log_3 y = x \log_3 3\)

\(\large \log_3 y = x \)

switch x and y

\(\large \log_3 x = y \)

\(\large y = \log_3 x \)

Answer 11

you need to knw few log rules to be able to work above :)
