domain of f(x)=(3x+5)/(2x^2-4x-6)

domain

f (x) = \frac{3 x + 5}{2 x ^{2} - 4 x - 6}

x < - 1 or - 1 < x < 3 or x > 3

Interval Notation

(- \infty, - 1) \cup (- 1, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = - 1

The function domain

x < - 1 or - 1 < x < 3 or x > 3

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

y = csc (x)

f (x) = \frac{x + 7}{x ^{2} - 49}

f (x) = x^{2} + 9 x + 2

f (x) = \frac{2 x - 3}{3}
