f⁻¹(x)= x-25
f(x)= x+25
To find the inverse of a function, you need to switch the x and y variables and then solve for y.
So, if f(x) = x-25, we can write it as:
y = x-25
Switching x and y, we get:
x = y-25
Solving for y, we can add 25 to both sides:
x+25 = y
Therefore, the inverse of f(x) = x-25 is:
f⁻¹(x) = x+25
Note that we used the notation f⁻¹(x) to represent the inverse function of f(x).
