Answer
a.)$ \lim\limits_{x \to\infty}$= -2
b.)$ \lim\limits_{x \to\infty}$= 2
c.)$ \lim\limits_{x \to 1}$= +$\infty$
d.) $ \lim\limits_{x \to3}$= -$\infty$
e.)x = 1, x=3, y=2, y=-2
Work Step by Step
a.) Using the graph, as x approaches positive infinity, the y value approaches -2.
b.) Using the graph, as x approaches negative infinity, the y value approaches 2.
c.) Using the graph, as the x value approaches positive one from both the left and the right, the y value extends to positive infinity.
d.) Using the graph, as the x value approaches positive three from both the left and right, the y value extends to negative infinity. \
e.)Equations are found by looking at the places in the graph where a line extends to either negative or positive infinity, either on the horizontal or vertical axis.
