Consider the function f(x) = x at x = 4. a) What is limx? x 4 b) Write down the precise definition for the above limit. Be sure to substitute for f(x), a, and L. c) For d) For e) For 1, find the 8 that satisfies the definition. 0.1, find the 8 that satisfies the definition. 0.01, find the 8 that satisfies the definition. f) For general (not a particular number), find the 5 which satisfies the defintion. Hints: Use the conjugate of x-2. Convince me that x+2>2. Convince me that +2. g) Graph y= and labeled. x around x = 4 with (4,2), x = 4+ 8, x = 4-8, y = 2 + , and y = 2 graphed Problem: Do the problem above for general a > 0.
