asymptotes of (x^2-9)/(x^2+4x-21)

asymptotes

\frac{x ^{2} - 9}{x ^{2} + 4 x - 21}

Vertical : x = - 7, Horizontal : y = 1

Solution steps

Vertical asymptotes of

\frac{x ^{2} - 9}{x ^{2} + 4 x - 21} : x = - 7

Horizontal Asymptotes of

\frac{x ^{2} - 9}{x ^{2} + 4 x - 21} : y = 1

Slant Asymptotes of

\frac{x ^{2} - 9}{x ^{2} + 4 x - 21} :

None

Vertical : x = - 7, Horizontal : y = 1

y = x^{2} + 4 x

f (x) = 2 x + 2 y - 8 = 0

f (x) = ln (x - 8)

18 x^{2} + 14 x

f (x) = \frac{1}{2 x - 6}
