domain of-(2x)/((x^2-49)^2)

domain

- \frac{2 x}{( x ^{2} - 49 ) ^{2}}

x < - 7 or - 7 < x < 7 or x > 7

Interval Notation

(- \infty, - 7) \cup (- 7, 7) \cup (7, \infty)

Solution steps

Find undefined (singularity) points:

x = 7, x = - 7

The function domain

x < - 7 or - 7 < x < 7 or x > 7

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

sin^{2} (x) + cos (x)

26 x^{5}

sin (x) + 2

f (x) = \frac{1}{x} e^{- x}
