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

domain

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

x < - 7 or x > - 7

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

f (x) = 8 - 3 x^{3}

x^{2} - 2 x - 6

x^{3} - 2

(- 5, - 4), (5, - 10)

\frac{2 x + 1}{( x ^{2} + 1 ) ^{1.5}}

What is the domain of f(x)=(x^2)/(x+7) ?
The domain of f(x)=(x^2)/(x+7) is x<-7\lor x>-7
