Math Problem Statement
Consider the following function. g(t) = t
sqrt8 − t , t < 7 Find g'(t). g'(t) =
Excluding any values not in the domain of g, for what values of c is g'(c) = 0 or undefined? (Enter your answers as a comma-separated list.) c =
Give the critical numbers of the function. (Enter your answers as a comma-separated list.) t =
Solution
Let's tackle this problem step by step. We'll first find the derivative , then determine the values of where or is undefined, and finally identify the critical numbers of the function.
1. Finding
The function is given by: To find , we can use the product rule of differentiation. The product rule states that if you have two functions and , then:
In our case:
Let's find the derivatives and :
For : Using the chain rule:
Now applying the product rule:
2. Finding values of where or undefined
To find where : The numerator must be zero:
To find where is undefined, we need to consider the denominator:
However, as given in the problem, so is outside the domain of and we exclude it.
So the values where or undefined are:
3. Critical numbers of the function
Critical numbers occur where or is undefined. We have already found:
Thus, the critical numbers of the function are:
