domain of f(x)=2x^2+6

domain

f (x) = 2 x^{2} + 6

- \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) = 2 x^{2} + 3 x - 2

f (x) = 3 x + 2, - 3 < x < 5

\frac{1}{1.8 x - 3.6 x ^{2}}

f (x) = e^{x + 3}

f (x) = e^{x + 1}
