Communication (14 marks) True/False Indicate whether the statement is true or false. 15. The instantaneous rate of change is determined by finding the difference quotient over a very small interval. 16. A limit exists if both the right-hand and left-hand limits are equal. 17. A jump discontinuity occurs when a function jumps over the x-axis. 18. A vertical asymptote can be found by solving the numerator equal to zero in a rational function. 19. A piecewise function always has a jump discontinuity. 20. Functions that have an indeterminate form when evaluating a limit can always be simplified by factoring. Completion Complete each statement. 21. A one-sided limit can be used to determine the behaviour of a graph on either side of a 22. A graph is if the left-hand limit does not equal the right-hand limit as x -> a. 23. The derivative of a function represents the of the tangent at any point on the function. 24. The limit of a function at x = a may exist even though the function is at x = a. 25. If the derivative does not exist at a point on the curve, the function is at that x-value. 26. Distinguish between average and instantaneous rate of change, use an appropriate example to support your
