Question
Find the critical numbers of the function.
(Enter your answers as a comma-separated list.)
Solution
To find the critical numbers of the function g(t) = t^5 - t, we first need to find the derivative of the function.
The derivative of t^5 is 5t^4 and the derivative of -t is -1. So, the derivative of the function g(t) = t^5 - t is g'(t) = 5t^4 - 1.
Next, we set the derivative equal to zero and solve for t:
5t^4 - 1 = 0 5t^4 = 1 t^4 = 1/5 t = ±(1/5)^(1/4)
However, we are given that t < 4. So, the only critical number within the given domain is t = -(1/5)^(1/4).
