domain of f(x)=(15x^2)/(x+5)

domain

f (x) = \frac{15 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

f (x) = 3 x^{2} - 2 x + 1

(- 2, 1), (1, 3)

\frac{3 x - 6}{7}

f (x) = x + 4 + 5

g (x) = x^{6} - 9 x^{4}

What is the domain of f(x)=(15x^2)/(x+5) ?
The domain of f(x)=(15x^2)/(x+5) is x<-5\lor x>-5
