domain of (-2)/(x^2+3x-28)

domain

\frac{- 2}{x ^{2} + 3 x - 28}

x < - 7 or - 7 < x < 4 or x > 4

Interval Notation

(- \infty, - 7) \cup (- 7, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 7

The function domain

x < - 7 or - 7 < x < 4 or x > 4

\frac{x + 8}{x ( x + 11 )}

f (x) = (2 x - 1) + (- 5 x^{2})

x^{4} - x^{3} - 15 x^{2} - 23 x - 10

y = 2^{x} + 2^{y} = 2

\frac{2 x ^{2} - 7 x - 4}{x - 4}
