1. To two decimal places, find the value of k that will make the function f(x) continuous everywhere. f(x) = 5x +k, xS-5 kx2 -3, x>-5 (4 points) 22.00 O -0.92 O -1.76 None of these x +5 2. Where is f(X) = - x2 +9x +20 discontinuous? (4 points) -4 O 5 Of(x) is continuous everywhere O -5, -43. Is the function f(x) = 2x +1, x54 (x' +12, x> & continuous? (4 points) Yes No 4. List the discontinuities for the function f(x) = cot( 2 ). (4 points) On( # ), where n is an integer On( " ), where n is an integer 3TT 7 -), where n is an integer There are no discontinuities. 5. Which of the following is true for f(x) = - ? (4 points) x - 3 There is a removable discontinuity at x = 3. There is a non-removable discontinuity at x = 3. O The function is continuous for all real numbers
