f(x)=(x-9)/(x^2-81)

Solution

f (x) = \frac{x - 9}{x ^{2} - 81}

Solution

Domain : x < - 9 or - 9 < x < 9 or x > 9

Range : f (x) < 0 or 0 < f (x) < \frac{1}{18} or f (x) > \frac{1}{18}

Y Intercepts : (0, \frac{1}{9})

Asymptotes : Vertical x = - 9, Horizontal y = 0

Extreme Points : None

+1

Interval Notation

Domain : (- \infty, - 9) \cup (- 9, 9) \cup (9, \infty)

Range : (- \infty, 0) \cup (0, \frac{1}{18}) \cup (\frac{1}{18}, \infty)

y= 1/(\sqrt[3]{x^2)}

f (x) = (x)

y = cos (x - π) - 2

f(x)=2x^3-2x^2+1

f (x) = 2 x^{3} - 2 x^{2} + 1
