question 3 · 1 point\nwhat is the horizontal asymptote of the graph of ( f(x)=\frac{9 x^{2}+2}{x^{2}+x} )?\ngive your answer in the form ( y=a ).\nprovide your answer below:
Answer
Explanation:
Step1: Divide numerator and denominator by (x^{2})
$$\lim_{x\rightarrow\pm\infty}\frac{9x^{2}+2}{x^{2}+x}=\lim_{x\rightarrow\pm\infty}\frac{9+\frac{2}{x^{2}}}{1 + \frac{1}{x}}$$
Step2: Evaluate the limit
As (x\rightarrow\pm\infty), (\frac{2}{x^{2}}\rightarrow0) and (\frac{1}{x}\rightarrow0). So (\lim_{x\rightarrow\pm\infty}\frac{9+\frac{2}{x^{2}}}{1+\frac{1}{x}}=\frac{9 + 0}{1+0}=9)
Answer:
(y = 9)
