What is the inverse of the function f(x) =(x/9) + 2?
Solution:
Given f(x) = (x/9) + 2
A function is defined as a relationship between one variable (the independent variable) and another variable (the dependent variable)
Let y = f(x)
y = z (x/9) + 2 ⇒ y - 2 = x/9
x = 9(y - 2)
We need to swap the x,y to get the inverse of f(x)
y = 9(x - 2)
This is in terms of y, so we can write x = f(y)
Hence, y = f-1(x) = 9(x - 2)
Therefore, the inverse of the given function is 9(x - 2)
What is the inverse of the function f(x) = (x/9) + 2?
Summary:
The inverse of the function f(x) = (x/9) + 2 is 9(x - 2).
