When f(x) increases without bound as x approaches c we write ( 29 x c lim f x = ∞
Note that this means ( 29 x c lim f x - = ∞ ( 29 x c lim f x + = ∞ and

Unformatted text preview: to answer a limit problem, we are still saying that the limit does not exist . ∞ ∞ If but then we can only say that ( 29 x c lim f x-→ = ∞ ( 29 x c lim f x + → = - ∞ ( 29 x c lim f x does not exist → does not exist x lim x → - 4 1 4...
