Calculus Home work Due Monday 16, XXXXXXXXXXLet f(x) = 3x2 - 5x + 2. Evaluate limx?-2 f(x). 2. Calculate limx?2 x2-4 x XXXXXXXXXXCalculate limt?1 5t2+6t+1 8t XXXXXXXXXXCalculate limx?3vx XXXXXXXXXX
5. Let f(x) = 3b v4b+1-1. Find limb?2 f(b) and limb?0 f(b). The first limit is very easy, the second requires some manipulation on your part.
6. (One-sided limits)
Let f(x) =
0 if x = 2 v25 - x2 if 2
Compute the following limits (a) limx?5- f(x), (b)limx?5+ f(x), (c)limx?5 f(x) ,limx?2- f(x), (d)limx?2+ f(x), (e)limx?2 f(x), (f) limx?100 f(x) 7. Calculate limh?0 v16+h-4 h 8.Assume limx?3 g(x) and f(x) = g(x) whenever x =? 3. What is limx?3 f(x)? Explain your answer.
Note that all these problems are from Section 2.3. Pleasee work out as many as you can from this section. I can put too many problems on the homework–I expect you to workout as many problems as you can from the Book.
