domain of f(t)=2t+t^2

domain

f (t) = 2 t + t^{2}

- \infty < t < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < t < \infty

f (x) = 4 x + 12 + \frac{1}{x + 2}

f (x) = 3 (x - 4)^{2} - 8

\frac{x ^{2} - 4}{x ^{2} + 4}

f (x) = - 5 + 8 x - x^{2}

\frac{x ^{2} - 4}{x ^{2} + 6}

What is the domain of f(t)=2t+t^2 ?
The domain of f(t)=2t+t^2 is -infinity <t<infinity
