Chapter 3.1, Problem 42E

Let f(x) be a piecewise function defined by - 6x + a if x - 3 What should be the values of a and b for f(x) to be continuous at x = -3? (A) a = 4, b = 2 B) a = 4, b = -4 a = -50, b = 2 D a =-50, b = -4

Let f(x) be the function x + 5 for x 2.

2. Evaluate lim,. 3. Find the domain of the function g(x) = v1- x In x . 4. Find f'(x), if f(x) = (2x – 8x²)-²(3x + 1).
