Graph the Rational Function f(X) = -X^2-7X-4/X=3. Please show graphing points

Question

anonymous · Answer

x+3
not x=3 sorry

anonymous · Answer

$$f(x) = -x^{2}-7x-\frac{4}{x}-3$$

Is that the equation? Or is it this?

$$f(x) = -x^{2}-7x-\frac{4}{x-3}$$

Or something else?

anonymous · Answer

$$-x^2-7x-4\div x+3$$

anonymous · Answer

so $$-x^2 - 7x -4$$  ----------     $$x+3$$

FYI, click equation below and use frac{}{}, example: frac{-x^{2}-7x-4}{x+3} turns into: $$\frac{-x^{2}-7x-4}{x+3}$$ This is one of those times where there's not much else to do but to put it into a graphing calculator: http://www.wolframalpha.com/input/?i=%28%E2%88%92x%5E2%E2%88%927x%E2%88%924%29%2F%28x%2B3+%29

well you could try estimating the positions of the curve to get a general shape of the actual graph using an interval chart.
