Prove the statement using the ε, δ definition of a limit. Prove the statement using the ε, definition of a limit. lim x → 1 6 + 4x 5 = 2 Given a > 0, we need ---Select--- such that if 0 < 1x – 1< 8, then 6 + 4x 5 2. ---Select--- But 6 + 4x 5 21 < E 4x - 4 5 <E |x – 1< E = [X – 1] < ---Select--- So if we...

Format requirement: Question 3. E-6 Proof (Show Working) 10 points 249 Show that f:RR defined by f(x) is continuous at x = 7 using only r +3 cosa the epsilon-delta definition of continuity. Note that we want you to do it the hard way: you are not allowed to use the limit laws or the combination of continuous functions theorem or similar. You must give an 'e-δ style proof Solution: Let ε > 0 be given and choose δ =...
A graphing calculator is recommended. For the limit lim x → 2 (x3 − 4x + 7) = 7 illustrate the definition by finding the largest possible values of δ that correspond to ε = 0.2 and ε = 0.1. (Round your answers to four decimal places.) ε = 0.2 δ = ε = 0.1 δ =

2. Use the ε - δ definition for the limit to prove that limx→-2 (4x - 3) = -113. Use the limit definition of the derivative to find the derivative of the function f(x) = √(4x + 1)4. Find the equation of the tangent line to the curve ve y = (1 + 2x) 10 at the point (-1,1).
Prove in the Hilbert deductive system the expression given in Problem 3.8 of the textbook: The first two steps of the proof, as well as the inference rule to be used in the third step, are given. You are required to complete the third step and give the subsequent steps of the proof. Assumption 2. (-A, -B-A)B-A Assumption 3. 2, contrapositive rule (2) Prove in the Hilbert deductive system the expression given in Problem 3.8 of the textbook: The first...
3) Complete the following to prove lim (4x – 3)= 5 using the epsilon-delta definition of a limit. x2 Part 1: Analysis (i.e. "guess” a 8) For every we need to if then (Complete these steps as you want in order to find delta.) This suggests that we should choose Part 2: Proof: (show that this choice of satisfies the definition of a limit). Given choose If then Thus, if , then Therefore, by Q.E.D.
