domain of f(x)=(4x+3)/(x^2-1)

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

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

f (x) = \frac{4 - x ^{2}}{x - 1}

f (x) = 4 (2^{- 2 x + 7}) - 5

f (x) = \frac{1 - x}{x ^{2} - 1}

- x^{2} + x - 2

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