Questions & Answers

Q: What is the function being differentiated in the content?

The function being differentiated is f(x) = x times square root of 8 minus x to the second power.

Q: What rule is used to take the derivative of the function?

The product rule is used to find the derivative of the given function.

Q: How is the derivative of the square root function calculated?

The derivative of the square root function is found by applying the chain rule, using the reciprocal of twice the square root of the quantity inside.

Q: How is the chain rule applied in this context?

The chain rule is used to take the derivative of the inner function, which is 8 minus x to the second power. The derivative of 8 is 0, and the derivative of -x to the second power is -2x.
