domain of 5x^2+2x-8

domain

5 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

5 x^{2} + 2 x - 4

f (x) = \frac{3 x ^{2} - 21 x}{6 x ^{2} - 39 x - 21}

- 2 x^{4} + 5 x^{2}

f (x) = \frac{1}{5} (x) - 6

f (x) = \frac{x - 4}{x ^{2} + 8 x - 20}

What is the domain of 5x^2+2x-8 ?
The domain of 5x^2+2x-8 is -infinity <x<infinity
