An asymptote is a line that a curve gets close to but doesn't touch.

The Solution to 17.

Question 17 is a graph of a rational function. The two asymptotes of the graph are perpendicular to each other. Remember the definition of an asymptote. The graph and asymptote never touch each other.

Domain: Real values of x such that $x\neq -2$

Range: Real values of y such that $y\neq -4$

The Solution to 18.

Question 18 is a graph of a square root function. For values that radicand is positive, the graph is drawn.

Domain: Real values of x such that $x\geq -5$

Range: Real values of y such that $y\geq -5$
