Try another version of this question When demonstrating that `lim_(x to -1)2 x + 2 =0` with `epsilon=0.4`, which of the following `delta`-values suffices? Get help: Box 1: Select all correct answers
Recall that to satisfy the definition of a limit, the chosen `delta` must ensure that for every `x` within `delta` of `-1`, the absolute difference between `2 x + 2` and `0` is less than `epsilon`.
`delta = 1/15`
`delta = 1/5`
`delta = 1/25`
