domain of f(x)=3x^2+x-8

domain

f (x) = 3 x^{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) = \frac{x ^{2} + 2 x - 5}{x ^{3} - 4 x ^{2} + 3 x}

f (x) = 3 x^{2} + x - 1

lo g_{10} (3 x + 6)

f (- 3) = \frac{2 x ^{2}}{3 x - 5}

5 x + 15

What is the domain of f(x)=3x^2+x-8 ?
The domain of f(x)=3x^2+x-8 is -infinity <x<infinity
