Answer
The derivative of the function is \(\frac{1}{3}\).
1Step 1: Define the function
Firstly, identify the function which is \(g(s)=\frac{1}{3} s+2\).
2Step 2: Apply the limit definition of derivative
Use the definition of the derivative which is the limit as h approaches 0 of (f(x+h) - f(x))/h. So in this case, (g(s+h) - g(s))/h is used.
3Step 3: Calculate g(s + h)
Calculate g(s + h) by replacing every s in the function with (s + h) which gives \(\frac{1}{3} (s + h) + 2\).
4Step 4: Substitute into the derivative definition
Substitute g(s + h) and g(s) into the derivative definition to get \([ \frac{1}{3} (s + h) + 2 - ( \frac{1}{3} s + 2 ) ] / h\). Simplify this to get \(\frac{1}{3}\).
5Step 5: Calculate the limit
As this doesn't depend on h anymore, the limit as h approaches 0 is simply \(\frac{1}{3}\).
