What is the inverse function of f(x)=2x-1

Goshia [24]

Step-by-step explanation:

Given

f(x) = 2x - 1

f^-1 (x) = ?

Now

Let y = f(x)

or y = 2x - 1

Interchanging the role of x and y

x = 2y - 1

x + 1 = 2y

y = x + 1

Therefore f^-1(x) = x + 1

Hope it will help you :)

5x - 2y = 18 -5x + 3y = -22

jeka94

Add the two equations
since the 5x and -5x cancel out
you get y=-4

plug y=-4 into the first equation
solve for x
x=2

THE ANSWER IS: (2,-4)
