If F(x) is an odd function and the graph of f(x) included points in quandrant IV which statement about must be true

Need on this geometry question. explain how you did it.

700 miles the train takes 5 hours to a travel the distance at what unit rate is the train traveling?

The graph of the the function f(x) is given below. find [tex]\lim_{x \to 0\zero} f(x)[/tex] [tex]\lim_{x \to 1+\oneplus} f(x)[/tex] [tex]\lim_{x \to 0-\zeroneg} f(x)[/tex]
