Answer:
The answer is
f-¹(x) = x + 2
Explanation:
To find the inverse of f(x) equate f(x) to y
That's
y = f(x)
y = x - 2
Next interchange the terms.
That's x becomes y and y becomes x
We have
x = y - 2
Make y the subject
Send 2 to the left side of the equation
y = x + 2
We have the final answer as
f-¹(x) = x + 2
