The given function is,
.
Or, 
To find the inverse of a function, first step is to switch x and y. Therefore,
Next stpe is to solve the above equation for y t get the inverse f f(x). Hence, multiply each sides by y + 5 to get rid of fraction form. So,
xy + 5x = 2y - 1
xy = 2y - 1 - 5x Subtract 5x from each sides to isolate y.
xy - 2y = -5x - 1 Subtract 2y from each sides.
y(x - 2) = -5x -1 Take out the common factor y.
Divide each sides by x-2.
So, 
Now when we will compare 
with 
then we will get a = -5, b = -1, c = 1 and d=-2
So, 
Hope this helps you!

Step-by-step explanation:
There are four important oceanic zones where plants and mammals survive in the ocean. The four significant zones are open ocean zone, intertidal zone, neritic zone, and benthic zone.There are four ocean zones. The sunlight zone, twilight zone, midnight zone, and abyssal zone.
As per the given information;
Bacteria triples every month.
Originally, there were 4 bacterial cells.
We are suppose to find how many there will be after 15 months.
Hence we can say , the number of bacteria after n month can be given using the exponential growth function
So number of bacteria after 15 month will be
