Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Answer:
Step-by-step explanation:
I hope this helps you
7.log2 (x)=15.log2 (2)
log2 (x)^7=log2 (2)^15
x^7=2^15
(x^7)^1/7=(2^15)^1/7
x=2^15/7
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
