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

asymptotes

f (x) = \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

- 1 - 4 cos (2 x)

f (x) = (x + 3)^{2} - 4

f (x) = x^{2} - 16

4 x + 7 y = 4 y - 7
