(a) If possible, approximate each of the following limits. Clearly indicate any limits approaching co. i) lim f(x) = ii) lim f(x) = x-+1+ -NWDUO iii) lim f (@) = iv) f (1) = 1-+1 v) lim f(@) = vi) lim f(x) = I+-2- -5 -3 -2 -1 1 2 3 14 5 6 vii) lim f(c) = vill) f (-2) = -2" -2 -3 ix) lin f(@) = x) lim f (@) = T-+4+ T+4- -4 xi) lim f (x) = xii) f (-4) = I-+4 (b) i. Use your results from part (a) to discuss the continuity of f(x) at r = -2. ii. Use your results from part (a) to discuss the continuity of f(x) at r = 1
