domain of f(x)=e^{-2t}

domain

f (x) = e^{- 2 t}

- \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) = - 2 x^{2} + 5 x - 6

(6, 4), (4, \frac{5}{3})

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

(2, - 4), (8, 4)

f (x) = a^{x}
