For what values of x will the function, f(x) = a) -6,0 b) -6, -3,0 x-3 x3+3x²-18x c) -6,0,3 be discontinuous? d) -3, 0, 6 True or False: [4 Marks] 6. If the limit exists at x = a then the function is continuous at x = a. 7. A removable discontinuity is the only discontinuity in which the limit exists. 8. A cusp is not a discontinuity but does result in the derivative not existing. 9. The reason we use the limit as h→0 to find the slope is because A x →0
