Solve the following math problem efficiently and clearly:

- For simple problems (2 steps or fewer):
Provide a concise solution with minimal explanation.

- For complex problems (3 steps or more):
Use this step-by-step format:

## Step 1: [Concise description]
[Brief explanation and calculations]

## Step 2: [Concise description]
[Brief explanation and calculations]

...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: The graph of $y = \frac{p(x)}{q(x)}$ is shown below, where $p(x)$ is linear and $q(x)$ is quadratic.  (Assume that the grid lines are at integers.)

unitsize(0.6 cm);

real func (real x) {
  return (2*x/((x - 2)*(x + 3)));
}

int i;

for (i = -5; i <= 5; ++i) {
  draw((i,-5)--(i,5),gray(0.7));
  draw((-5,i)--(5,i),gray(0.7));
}

draw((-5,0)--(5,0));
draw((0,-5)--(0,5));
draw((-3,-5)--(-3,5),dashed);
draw((2,-5)--(2,5),dashed);
draw(graph(func,-5,-3.1),red);
draw(graph(func,-2.9,1.9),red);
draw(graph(func,2.1,5),red);
