Accepted Answer

$$-3$$

Question 8

Which of the following best describes the use of L'Hospital's Rule?

Accepted Answer

It is used to evaluate limits that result in indeterminate forms like $$\frac{0}{0} or$$ $$\frac{\infty}{\infty}.$$

Question 11

Given the function $$f(x) = x^2$ - 4 on$$ $$[0, 3]$$, and using a midpoint Riemann sum with $$n = 6$$, what is the width $$\Delta x of $$each subinterval?

Accepted Answer

$$\Delta x = 0.5$$

Question 12

Which of the following is the correct linear approximation (linearization) of $$f(x) = \sqrt{x+3} at$$ $$a = 1$$?

Accepted Answer

$$L(x) = 2 + \frac{1}{4}(x-1)$$

Accepted Answer

$$-1$$

Question 14

Accepted Answer

$$f(x) is $$increasing on that interval.

Question 17

Which of the following is the correct application of the Fundamental Theorem of Calculus, Part 1?

Accepted Answer
