PLS HELP ASAP ON ALL ASKED QUESTIONS PLS. this is T/F questions 13. The limit will never exist at adiscontinuity.14. The average rate of change is the slope of the tangent at f(a).15. A jump discontinuity occurs when a function jumps over the x-axis.16. A piecewise function always has a jump discontinuity.17. An infinite discontinuity means a function is merely a set of scattered points.18. The instantaneous rate of change is determined by finding the difference quotient over a very small interval.19. Functions that have an indeterminate form when evaluating a limit can always be simplified by factoring.20. The derivative can be used to calculate the slope of the tangent to any point on a function.21. For a parabola, the instantaneous and average rate are equal
