domain of (2x)/(x^2-25)

domain

\frac{2 x}{x ^{2} - 25}

x < - 5 or - 5 < x < 5 or x > 5

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 5, x = - 5

The function domain

x < - 5 or - 5 < x < 5 or x > 5

f (x) = lo g_{2} (- x)

f (x) = x^{2} + y^{2} = 81

f (x) = x^{2} + y^{2} = 64

f (x) = \frac{2}{( x - 8 ) ( x + 7 )}

f (x) = [- 2.2]
