I would like help with these questions please and thank you .

7. (5pts) Suppose f(x) is continuous and that lim f(x) =5. What is f(2) ? x-2 8. (5pts) Suppose f(x) is continuous and that f (-4) =1. What is lim f(x) ? 9. (5pts) Suppose lim f(x) = -3 and lim g(x) = 7. What is lim (f (x) + g(x)) ? 10. (5pts) Suppose -x' +3s f(x) Sx +3 for all x . Evaluate lim f(x) . For number 11 and 12 show all work. BOX YOUR ANSWER. 11. (40pts) Compute each limit or show that it does not exist. A limit may be too. 1 1 a) lim x 4 x4 x+4 (x approaches negative 4) b) lim x(x + 3) x-2 (x+ 1)(2 - x) x - 5x + 6 c) lim x - 3 d) lim 7x+6 so Vx2 + 3x 2x + 5 , x3 Part A. Is f continuous at 3 from the left? Part B. How about from the right? Part C. Is f continuous at 3
