Assignment:
Q1. Use the definition of f(x)→∞ as x →∞ to show that f(x) = x + 2 →∞ as x →∞
Q2. (a) Show that f(x) = 3/x + 2 tends to ∞ as x → –2+ .
(b) Show that f(x) = 1/ 4 - x tends to ∞ as x → 4–
Q3. Let f(x) = {.4 when x 5
{ 0 when x > 5
Show that f is not continuous at x = 5.
Provide complete and step by step solution for the question and show calculations and use formulas.
