f%28x%29=%28x%5E3-7x-6%29%2F%28x%5E2%2B3x%2B2%29 Start with the given equation



f%28x%29=%28%28x-3%29%28x%2B2%29%28x%2B1%29%29%2F%28x%5E2%2B3x%2B2%29 Factor the numerator (hint: use the graph to help you factor)


f%28x%29=%28%28x-3%29%28x%2B2%29%28x%2B1%29%29%2F%28%28x%2B2%29%28x%2B1%29%29 Factor the denominator

f%28x%29=x-3 Simplify. Take note that x%3C%3E-2 or x%3C%3E-1
