domain of y=(x^2-25)/(x+5)

domain

y = \frac{x ^{2} - 25}{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) = lo g_{10} (5) (x - 2) + 1

\frac{x ^{2}}{( x - 4 ) ( x + 3 ) ( x - 1 )}

h (t) = \frac{cos ^{2} ( t )}{1 - t ^{2}}

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

f (x) = 24 - 6 x

What is the domain of y=(x^2-25)/(x+5) ?
The domain of y=(x^2-25)/(x+5) is x<-5\lor x>-5
