The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.
What is a Function?
A function is a law that relates two variables namely, a dependent and an independent variable.
A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.
The function is f(x) = 2x -1
The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.
Patel replaced f(x) by y, y = 2x -1
He then switched x and y, x = 2y -1
The next step is to solve the equation for y.
2y = x +1
y = (x +1) /2
