domain of F(x)= 4/(x^2-x-2)

domain

F (x) = \frac{4}{x ^{2} - x - 2}

x < - 1 or - 1 < x < 2 or x > 2

Interval Notation

(- \infty, - 1) \cup (- 1, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 1

The function domain

x < - 1 or - 1 < x < 2 or x > 2

ln (\frac{x}{x + 1})

f (x) = 5 (x - \frac{16}{3})^{2} + 16

1 + \frac{1}{x ^{2}}

f (x) = (x + 1) (2 x + 3)

f (x) = lo g_{10} (x^{2} - 9 x)
