domain of f(x)=(x^2+3x-4)/(x^2+5x-14)

domain

f (x) = \frac{x ^{2} + 3 x - 4}{x ^{2} + 5 x - 14}

x < - 7 or - 7 < x < 2 or x > 2

Interval Notation

(- \infty, - 7) \cup (- 7, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = - 7

The function domain

x < - 7 or - 7 < x < 2 or x > 2

3 x - 4

y = 3 - x^{3}

x - 8

f (x) = x^{3} + x

21 x + 7 y = 14
