domain of f(x)=ln(1+((x+1))/(x+4))

domain

f (x) = ln (1 + \frac{( x + 1 )}{x + 4})

x < - 4 or x > - \frac{5}{2}

Interval Notation

(- \infty, - 4) \cup (- \frac{5}{2}, \infty)

Solution steps

Find positive values for logs:

x < - 4 or x > - \frac{5}{2}

Find undefined (singularity) points:

x = - 4

Combine real regions and undefined points for final function domain

x < - 4 or x > - \frac{5}{2}

f (x) = x^{5} + 5 x^{4}

f (x) = 6 x + 9

f (x) = x^{3} - 7

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

6 sin (\frac{π}{3} x) + 1

What is the domain of f(x)=ln(1+((x+1))/(x+4)) ?
The domain of f(x)=ln(1+((x+1))/(x+4)) is x<-4\lor x>-5/2
