Select the correct equation for the following graph: $f(x) = \frac{2(x+3)}{(x-2)(x+1)}$ $f(x) = \frac{(x-2)(x+1)}{2(x+3)}$ $f(x) = \frac{(x+2)(x-1)}{2(x-3)}$ $f(x) = \frac{2(x-3)}{(x+2)(x-1)}$

Step 1
This means the denominator must have factors of $(x+2)$ and $(x-1)$. The graph has a zero at $x=3$. This means the numerator must have a factor of $(x-3)$. Therefore, the equation must be of the form $f(x) = \frac{c(x-3)}{(x+2)(x-1)}$ for some constant $c$. The Show more…

The equation for $f$ is given by the simplified expression that results after performing the indicated operation. Write the equation for $f$ and then graph the function. $$\frac{2}{x^{2}+3 x+2}-\frac{4}{x^{2}+4 x+3}$$
