For each of the following limits, a value of € is given. For each, give the largest value of 6 which makes the sentence: For all x € R, if 0 < x- c < 8 then |f(x) - L| < € a true sentence. (a) lim 5x6 = 9, where e = 1. x-3 (b) lim √x = 2, where € = 1. x-4 (c) lim [x] = 3, where = 1. (The function [x] is the "floor", or "integer XIT part" function, which outputs the greatest integer which is less than or equal to x.)

For each of the following limits, a value of ε (epsilon) is given. For each, give the largest value of δ (delta) which makes the sentence:

For all \( x \in \mathbb{R} \), if \( 0 < |x - c| < \delta \) then \( |f(x) - L| < \epsilon \)

a true sentence.

(a) \( \lim_{{x \to 3}} 5x - 6 = 9 \), where \( \epsilon = 1 \).

(b) \( \lim_{{x \to 4}} \sqrt{x} = 2 \), where \( \epsilon = 1 \).

(c) \( \lim_{{x \to \pi}} \lfloor x \rfloor = 3 \), where \( \epsilon = 1 \). (The function \( \lfloor x \rfloor \) is the "floor", or "integer part" function, which outputs the greatest integer which is less than or equal to \( x \).)
