Answer: second option
Step-by-step explanation:
To find the inverse function of the given function f(x):

You need to:
Substitute
into the function:

Now, you need to solve for "x", to do this, you must divide both sides of the function by 2:

Now, replace "x" with "y" and replace "y" with "x":

Therefore, substituting
you get:
or

Answer:
<u><em>5/8</em></u>
Step-by-step explanation:
first plug in for x & y, then solve. you should get 5/8
2 -2 +5 +0 / 2 +3 +5 -2
<u><em>5/8</em></u>
If you would like to know the solution to the equation, you can calculate this using the following steps:
4/5n - 3/5 = 1/5n /*5n
4 - 3/5 * 5n = 1
4 - 3n = 1
4 - 1 = 3n
3 = 3n
n = 1
The correct result would be n = 1.
