I need help. Thank you

1. Circle T or F for each of the following statements based on the graph of the relation f(x) shown below. Statement True False a) f(x) is a function T F lim f(x) = 3 b) *+2 T F lim f(x) does not exist T F C) *-4 lim f(x) = 0 T F d) 2. State the type of discontinuity for each graph below. al b) 2 -16 -2 0 12 0 2 -2 3. State the formal requirements for a function to be continuous when x = a.lim sin x 4. Explain why the following limit does not exist: * * 5. Determine the limit of each of the following functions if they exist: lim x' +2x -15 3- vx+11 lim a) x' -9 b) +4-2 x+2 lim x +kx -24 6. Given that * *3 x- 3 exists, determine the value of k, and then evaluate the limit. 7. Draw a sketch of f(x) on the grid provided that satisfies all of the following criteria: f(x) ; is a function -3 & 2 are zeroes lim f (x) =2 lim f(x) = -6 123456 78 9 X lim f(x) exists non-continuous at x = -5
