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

domain

f (x) = 4 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

\frac{2 x + 5}{x ^{3} - 8}

\frac{2}{r ^{2} + 1}

f (x) = 4 x^{2} + 7

f (x) = - 3 (x + 7) - 7

4 x^{3} - 12 x^{2}
