Final answer:
The question lacks adequate information to find the difference quotient of the function f(x) = √(4 - x²). The references provided do not offer the relevant steps for this calculation.
Step-by-step explanation:
The student asked to find the difference quotient of f(x) = √(4 - x²). The difference quotient, which is a way to compute the rate of change of a function, is given by the expression (f(x + h) - f(x)) / h as h approaches zero.
In this case, however, the options provided suggest that the student is looking to simplify the expression after substituting f(x + h) and f(x) without taking the limit as h approaches zero.
Unfortunately, the information given is not directly relevant to solving for the difference quotient of the provided function, and as such, it does not enable providing a step-by-step solution. Therefore, it is suggested that the student might need to provide the complete problem or seek additional guidance for calculating the difference quotient.
