Find the limit lim $2-x-2 C +2 2x2-4x = (a) does not exist ( b) 0 (c) ; (d) (e) V4 - x if x 2. (i) lim f (x) = (ii) lim f (x) = I-+0+ (iii) lim f(x) = (iv) lim f (x) = I-+2- I-+ 2+ 21. For what value of the constant K is the function f continuous on ( - 0o, co)? Kx + 7 for x - 2 f (z) = Kx2 - 5 for x > 2. (a) 5 ( b) 6 (c) 2 (d) - 3 (e) - 6 22. Determine where f (x) = 2x2-4x 1 -1-2 is continuous (a) Everywhere except x = 4, x = 1, x = 2 (b) Everywhere except x = 0, x = 1, x =2 (c) Everywhere except x = 2, x = 0 (d) Everywhere except x = 0 (e) The function f is continuous for all real numbers 23. Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or given an example that disaproves the statement. (1). If lim f(x) exist then f(x) must be defined at 3
