domain of f(x)=2x^2+4x-5

domain

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

- \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 - 1}{x ^{2}}

3 x

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

y = \frac{2}{3} x - 1

\frac{2}{7} x - 9
