Find a formula for the inverse of the function.y = e2 − x
Question
Find a formula for the inverse of the function.y = e2 − x
Solution
To find the inverse of the function y = e^(2-x), we need to follow these steps:
-
Swap x and y: x = e^(2-y)
-
Solve for y:
First, take the natural logarithm (ln) of both sides to get rid of the exponential on the right side:
ln(x) = ln(e^(2-y))
This simplifies to:
ln(x) = 2 - y
-
Solve for y by subtracting 2 from both sides and multiplying by -1:
y = 2 - ln(x)
So, the inverse of the function y = e^(2-x) is y = 2 - ln(x).
