6. True or False? Correct any false statements or say why they are false. a. A function cannot cross a horizontal asymptote. b. If f(a)=2, then lim ƒ(x) = 2. x→a T F T F

Explain why the function is discontinuous at the given number a. (Select all that apply.) 1 f(x) a = -5 X + 5 lim f(x) and lim f(x) are not finite, and are not equal. X→-5+ X--5 f(-5) and lim f(x) are finite, but are not equal. X→-5 lim f(x) does not exist. x--5 f(-5) is undefined. none of the above

Use the graph of the function to answer the questions a- d. a. f(1) = 10 b. lim f(x) = X-1 C. f(5) = %3D d. lim f(x) = x-5 -2 4. 10 2.

All work must be shown to receive full credit for a correct solution. Partial credit may be given if the correct work is shown and an incorrect answer is given. 1. Answer the following questions. Show your work = a. Find and simplify the difference quotient for the function ƒ(x): b. Find lim [Difference Quotient of f(x)]. h→0 1 x-4
