domain of f(x)=(x^2-3x-28)/(x+4)

domain

f (x) = \frac{x ^{2} - 3 x - 28}{x + 4}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

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

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

g (x) = x^{2} - 6 x

f (x) = (5 x - 1) \cdot (10 x - 9)

x^{2} - 10 x + 21

What is the domain of f(x)=(x^2-3x-28)/(x+4) ?
The domain of f(x)=(x^2-3x-28)/(x+4) is x<-4\lor x>-4
