The function f(x)=\frac{5x+2}{x-3}can be rewritten in the form f(x)=5+\frac{17}{x-3}. What is the end behavior of y=f(x)?

Rewrite the rational function g(x)={x^{2}+7x-12}{x+2} in the form g(x)=p(x)+\frac{r}{x+2}, where p(x) is a polynomial and r is an integer.

Match each polynomial with its end behavior as x gets larger and larger in the positive and negative directions. (Note: Some of the answer choices are not used and some answer choices are used more than once.)

Let the function P be defined by P(x)=x^{3}+2x^{2}-13x+10. Mai divides P(x) by x+5 and gets:
How could we tell by looking at the remainder that (x+5) is a factor?
