domain of f(x)=x^2+8x-20

domain

f (x) = x^{2} + 8 x - 20

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

- (\frac{1}{4})^{x} - 2

\frac{- 2 x ^{2} + 5 x - 1}{2 x - 1}

f (x) = x^{2} - 16 \cdot (x^{2} + x - 2)

\frac{x ^{3} - 27}{x}

What is the domain of f(x)=x^2+8x-20 ?
