domain of (2x^2+16x-18)/(x^2+x-6)

domain

\frac{2 x ^{2} + 16 x - 18}{x ^{2} + x - 6}

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 3

The function domain

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

3 cos (x - \frac{π}{4}) - 1

f (x) = x^{4} - 50 x^{2} + 4

f (x) = 2 x - 4

(12, 10), (14, - 1.5)

x - 1
