Solution

domain

f (x) = 3 + \frac{9}{x}

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

slope of y=-2x+8 slope

y = - 2 x + 8

critical x^7+x^2-15 critical points

x^{7} + x^{2} - 15

inverse of sqrt(1-x^2)inverse

1 - x^{2}

inverse of f(x)=x^2-3x+3 inverse

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

intercepts of f(x)=x^3-8x^2+9x+18=0 intercepts

f (x) = x^{3} - 8 x^{2} + 9 x + 18 = 0
