domain of f(x)=(3x^2+5x-6)/(x^2-9)

domain

f (x) = \frac{3 x ^{2} + 5 x - 6}{x ^{2} - 9}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 3, x = - 3

The function domain

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

y = tan (3 x)

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

f (x) = x^{2} ln (4 + 6 x)

f (x) = ∣ x ∣ + 2 x - 3

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