Question 214270
1) You have to plug them in or use a graphing calculator.
.
2) Asymptote= a straight line that is closely approached  but never touched by a curve.
 Take 1/(x+1) for example (the graph below). X can never be -1 (the vertical asymptote) because division by zero is not allowed. The end behavior of the function as x becomes very large (or very small) is that the lines get very close to the horizontal asymptote but never touch it. Note that there is a horizontal asymptote at y=0 also.
