5. For the function: f (x) = Note: you may use technology to do computations, create tables or graphs, and/or check your results. Technology may not be used to do Calculus operations such as derivatives. (a) Find f'(2) ( b ) Find f"(2) 6. A classmate asks for help on a Calculus problem. The problem states that " f(x) = b where "a" and "b" are constants. The problem asks whether f (x) is continuous at x = a, Explain to your classmate whether or not we can conclude that f(x) is continuous at x = a and how you know. You may use a diagram andfor example to aid your explanation. 7. Solve the following equation for the variable L: A = my2+- 8. Use the definition of the derivative (the difference quotient) to find the derivative of y = 3x at the point where x = 5
