domain of f(x)=(x^2)/(x+5)

domain

f (x) = \frac{x ^{2}}{x + 5}

x < - 5 or x > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

4 cos (x) + 1, 0 \leq x \leq 2 π

f (x) = - 10 - 2 x

f (x, y) = y^{2} - 1^{2}

y = \frac{x ^{3} - 4 x ^{2} + x + 6}{x + 1}

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

What is the domain of f(x)=(x^2)/(x+5) ?
The domain of f(x)=(x^2)/(x+5) is x<-5\lor x>-5
