domain of f(x)=x+7/x

Solution

domain

f (x) = x + \frac{7}{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

domain of f(x)=(x^2-8x+16)/(x-4)domain

f (x) = \frac{x ^{2} - 8 x + 16}{x - 4}

domain of y=(sqrt(x+1))/(x^2)domain

y = \frac{x + 1}{x ^{2}}

domain of f(x)=(3x+2)/(2x-3)domain

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

domain of f(x)=8x-16 domain

f (x) = 8 x - 16

domain of f(x)=(-4.2)domain

f (x) = (- 4.2)
