domain of y=(3x^2)/(x+5)

domain

y = \frac{3 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 sin (4 x)

\frac{1}{∣ x ^{2} - 7 ∣}

x e^{- 6 x}

f (x) = \frac{x + 9}{( x - 1 ) ( x - 7 )}

f (x) = 7 ln (x) + π

What is the domain of y=(3x^2)/(x+5) ?
The domain of y=(3x^2)/(x+5) is x<-5\lor x>-5
