domain of f(x)= 4/(x+3)

domain

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

x < - 3 or x > - 3

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

f (x) = \frac{( 6 - 2 x ^{2} )}{( x ^{2} - 16 )}

f (x) = x^{3} - 4 x

e^{t a n (x^{2})}

(35.23) (7.5)

x^{4} - 4 x^{3}

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