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

domain

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

- \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) = 3 x^{2} + 5 x - 9

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

f (x) = lo g_{10} (5 - 2 x)

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

ln (ln (x))

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