domain of 8/(7+x)

Solution

domain

\frac{8}{7 + x}

Solution

x < - 7 or x > - 7

+1

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

Popular Examples

periodicity of f(x)=4cos(2(x+pi/4))-3 periodicity

f (x) = 4 cos (2 (x + \frac{π}{4})) - 3

asymptotes of f(x)=x*e^{-1/x}asymptotes

f (x) = x \cdot e^{- \frac{1}{x}}

perpendicular y= 1/2 x-2 perpendicular

y = \frac{1}{2} x - 2

range of f(x)=|x|+1 range

f (x) = ∣ x ∣ + 1

domain of f(x)=sqrt(3)(x-9)domain

f (x) = 3 (x - 9)
