domain of f(x)=(x+7)/(x^2+14x+49)

domain

f (x) = \frac{x + 7}{x ^{2} + 14 x + 49}

x < - 7 or x > - 7

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

f (x) = (ln (x))^{l n (x)}

\frac{x ^{3}}{( 4 - x ) ^{2}}

4 x^{2} - 9

f (x) = x^{2} - 6 x + 9

f (x) = arccos (x^{2} - 3)

What is the domain of f(x)=(x+7)/(x^2+14x+49) ?
The domain of f(x)=(x+7)/(x^2+14x+49) is x<-7\lor x>-7
