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

domain

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

y = 2 x + 3

x^{2} - 2 x - 3

f (x) = 48 x - 3 x^{2}

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

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