What is lim ? X-0+ x

Question-10 x +5x + 6 If f(x) = , then answer the following: x² -4 a) lim f(x) x-2 b) State whether f(x) is continuous at x =-2

Give an example by sketching the graph of a function f that satisfies all the given conditions. lim (x--> -3) f(x)=+oo, lim (x--> -oo) f(x)=-2, f(0) = 0, f is even.

6. Evaluate lim F(x), where f is defined by F(x) =(picture)

( +3 ,x1 „x>1 g(x) exists? Justify. 1-1 f(x) a) Does lim f(x) + g(x) exists? Justify. b) Does lim

Given the graph of the function f below, Which of the following must be true? 3 lim lim A) lim B) lim C) f(x) = f(x) f(x) = 2 f(x) = 2 lim D) lim f(x) = 1 E) f(x) does not exist 2.

Don't use der

Is there any better explanation on how on answering the function?
