domain of f(x)=(x^2+7)/(x^2)

Solution

domain

f (x) = \frac{x ^{2} + 7}{x ^{2}}

Solution

x < 0 or x > 0

+1

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

vertices y=-x^2+4x vertices

y = - x^{2} + 4 x

inverse of y=4^x+8 inverse

y = 4^{x} + 8

domain of f(x)=sqrt(x^2-4x+3)domain

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

domain of 1/(sqrt(x-4))domain

\frac{1}{x - 4}

inverse of f(x)=(x-4)^2+2,x>= 4 inverse

f (x) = (x - 4)^{2} + 2, x \geq 4
