So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)We say "f inverse of y"So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2...

An inverse function reverses the method of a function. If, in algebra, f(x) = 2x, then inverse function of f(x) will be a function say f(y) = y/2. Graph, properties, types at BYJU’S
