domain of f(x)=2x^2+x-7

domain

f (x) = 2 x^{2} + x - 7

- \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

\frac{x - x + 2}{4 x + 1 - 3}

4 ln (3) \cdot 9^{x^{2}} x

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

f (x) = - 2 x^{3} + 6 x^{2} + 12

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

What is the domain of f(x)=2x^2+x-7 ?
The domain of f(x)=2x^2+x-7 is -infinity <x<infinity
