domain of f(x)=log_{10}(x^2+9x+8)

domain

f (x) = lo g_{10} (x^{2} + 9 x + 8)

x < - 8 or x > - 1

Interval Notation

(- \infty, - 8) \cup (- 1, \infty)

Solution steps

Find positive values for logs:

x < - 8 or x > - 1

The function domain

x < - 8 or x > - 1

\frac{2 x}{x - 4}

\frac{x}{- x + 4}

f (x) = - 3^{2}

e^{- x} + 1

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

What is the domain of f(x)=log_{10}(x^2+9x+8) ?
The domain of f(x)=log_{10}(x^2+9x+8) is x<-8\lor x>-1
