Evaluate the limit: lim *+ 3- X+3 . (A1.4) a. - O b. C. -1 d. -co 4. Evaluate the limit for the graph: lim A(x). (A1.3) *- 3- A 2 -4 2 0 2 -4 a. +Co C. -3 b . 1 d. - co The average rate of change of A(x) = mx + b over the interval -3 x 5 is (A1.2) a. 5 c. m b. -3 d. b 6. This function: (A1.5)4 2 -4 -2 0 2 4 x a. has a jump discontinuity c. has a removable discontinuity b. has an infinite discontinuity d. is continuous 7. A graph is if the left-hand limit does not equal the right-hand limit as x -> a. (A1.4) 8. The average rate of change is found using the (A1.2) 9. The instantaneous rate of change is found using . (A1.4) 10. The limit of a function at x = a may exist even though the function is at x = a. (A1.3) 11. When direct substitution of x = a into a limit results in , the limit is said to be of an form. (A1.5) 12. If a function is discontinuous, or has a cusp or a corner at x = a, then the function is at x = a. (A1.6)
