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

domain

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

x < - 2 or - 2 < x < 3 or x > 3

Interval Notation

(- \infty, - 2) \cup (- 2, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3, x = - 2

The function domain

x < - 2 or - 2 < x < 3 or x > 3

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

3 ln ∣ 3 x - 5 ∣ + 2

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

y = 3 x^{2} - 18 x + 30

- e^{x}
