What is the inverse of the function f(x) = x^4 + 12?

To find the inverse of the function f(x) = x4 + 12, we first need to express y in terms of x:

Let y = x4 + 12. To find the inverse, we switch x and y:

x = y4 + 12

Next, we solve for y:

  1. Subtract 12 from both sides:
  2. x – 12 = y4

  3. Now, take the fourth root of both sides:
  4. y = (x – 12)1/4

Thus, the inverse function is:

f-1(x) = (x – 12)1/4

To summarize, the inverse of the function f(x) = x4 + 12 is f-1(x) = (x – 12)1/4. This means that if you take a value, plug it into the original function, and then take that result and plug it into the inverse function, you will get back to your original input.
