Hi,
How would I graph this function please?
$\displaystyle y=-x^2/(2-x+4)$
Use long division:
That means: $\displaystyle y = \dfrac{x^2}{x-6} = \underbrace{x + 6}_{\text{term of slant asymptote}} + \dfrac{36}{x-6}$Code:36 x^2 ÷ (x - 6) = x + 6 + ----- -(x^2 - 6x) x-6 ------------- 6x -(6x - 36) ---------- 36
Keep in mind that a denominator must unequal zero.
have you had any instruction on the graphing of rational functions? if not, then you need to research the topic and do some example problems.
here's a link to get you started ...
