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)
What is the inverse of y = -x?The Inverse Process of a Function:The inverse function is a new function formed by the reversed process of the function. For this process, we have to exchange the symbols of the independent and dependent variables in the original function....
