domain of f(x)=4x^2+12x+5

domain

f (x) = 4 x^{2} + 12 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

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

f (x) = cos (x + 1)

f (x) = \frac{x}{9 x + 6}

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

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