domain of f(x)=5x^2

domain

f (x) = 5 x^{2}

- \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

f (x) = 4 x^{3} - 6 x^{2} + 5 x - 6

y = 2 x + 5

f (x) = \frac{x ^{2} - 2 x}{x ^{3} - 16 x}

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

f (x) = x^{2} + 8
