Find the inverse of each of the given functions

first, replace  

f

(

x

)

with  

y

. this is done to make the rest of the process easier.

replace every  

x

with a  

y

and replace every  

y

with an  

x

.

solve the equation from step 2 for  

y

. this is the step where mistakes are most often made so be careful with this step.

replace  

y

with  

f

−

1

(

x

)

. in other words, we’ve managed to find the inverse at this point!

verify your work by checking that

(

f

∘

f

−

1

)

(

x

)

=

x

and

(

f

−

1

∘

f

)

(

x

)

=

x

are both true. this work can sometimes be messy making it easy to make mistakes so again be careful.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
