Finding the inverse function:
We are given a function y = f(x). To find the inverse function, we exchange x with y in the original function, and then isolate y.
So
We are given the function:
So
Changing x with y
Now, we have to isolate y. So
We can apply the fifth root to both sides. So:
Answer:
4 or 4.75
Step-by-step explanation:
first we're going to convert the number into improper fractions.
7=
and 2
=
For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply x2, it'll equal the same number.
So now we have -
, 30-11= 19.
simplified is, 4
.
As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.
I hope this helps you!
