1. We write lim,-. /(x) =L provided the values of (b) lim /(@) = can be made as close to as desired, by (c) lim f() = taking values of sufficiently close to but not (d) lim f(x) = 2. We write lim, _.a- /(x) = +% provided increases without bound, as approaches from the left. 3. State what must be true about -2 lim (x) and lim f(x) in order for it to be the case that Figure Ex-4 lim /(x) = L 4. Use the accompanying graph of y = /(x) (-x
