domain of f(x)=(x^3)/(x^2-9)

Solution

domain

f (x) = \frac{x ^{3}}{x ^{2} - 9}

Solution

x < - 3 or - 3 < x < 3 or x > 3

+1

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

x < - 3 or - 3 < x < 3 or x > 3

Popular Examples

slope of 5x=y+3 slope

5 x = y + 3

domain of sqrt((3-x)/(x+2))domain

\frac{3 - x}{x + 2}

inverse of y=e^{x+2}inverse

y = e^{x + 2}

line (-1,6),(7,-2)line

(- 1, 6), (7, - 2)

intercepts of f(x)= 4/3 x-8 intercepts

f (x) = \frac{4}{3} x - 8
