domain of f(x)=[2(x+3)]^2+3

domain

f (x) = [2 (x + 3)]^{2} + 3

- \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) = \frac{9 - x ^{2}}{x + 1}

f (x) = (- 2.2)

f (x) = \frac{2}{x ^{3} + 27}

x - \frac{2 x - \frac{3}{3 x} - 2}{3 x} 4

y = x - \frac{4}{x}

What is the domain of f(x)=[2(x+3)]^2+3 ?
The domain of f(x)=[2(x+3)]^2+3 is -infinity <x<infinity
