1.
  • Consider the following statements:

I. f(c) is defined

II.  exists

III. 

We say "f is continuous at c" if the following statements hold:

-> I

2. Which of the statements is true about the function f graphed below? 

-> f is discontinuous at x = 1 because 

3. Let  

Identify all points at which <em>f</em> is discontinuous. -> x = 1, x = 2


4. Identify all points at which f is discontinuous. 

-> x = 1, x = -2

5. On which of the following intervals is f continuous? 

  -> (0,3)

6. On which of the following intervals is g discontinuous? 

  -> (3,4)

7. Let     

On which of the following intervals is f continuous?

-> (-2,0)

8. Let  

On which of the following intervals is f(x) continuous?

-> (-1,1)

9. Let f(x) = x + 1 and g(x) = x - 1. Which of the following statements is false?

-> The function f + g is continuous at x = 1.


10. Which of the following functions is not continuous? -> h(x) = tan(x)
