13. This function: 4 -2 0 a has a jump discontinuity C. has a removable discontinuity b . has an infinite discontinuity 2 is continuous 14. The domain of the function is 2 -4 -2 0 a. x 20 b. x > 1 C . XER d. X ER, | x 1 Communication (14 marks) Indicate whether the statement is true or false. 15. A difference quotient is used to calculate the slope of the secant at a general point. 16. The instantaneous rate of change is determined by finding the difference quotient over a very small interval. 17. A limit exists if both the right-hand and left-hand limits are equal. 18. A jump discontinuity occurs when a function jumps over the x-axis. 19 . An infinite discontinuity means a function is merely a set of scattered points. 20. A vertical asymptote can be found by solving the numerator equal to zero in a rational function. 21. A piecewise function always has a jump discontinuity. 22 . Functions that have an indeterminate form when evaluating a limit can always be simplified by factoring. Page 4 of 7
