If f(x)=2x-3/5 which of the following is the inverse of f (x)

g(x)=(x+3/5)/2

Step-by-step explanation:

When f(g(x)) and (g(f(x)) both equal x, they are inverses.

f(x)=2x-3/5

y=2x-3/5

x=2y-3/5

x+3/5=2y

(x+3/5)/2=y

(x+3/5)/2=g(x)

For this case we must find the inverse of the following function:

We change f(x) by y:

We exchange the variables:

We cleared "y":

Adding to both sides of the equation:

DIviding between 2 to both sides of the equation:

We change y for:

-14 is the answer
