domain of e^{-7t}

domain

e^{- 7 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) = x + 15

f (x) = 3 x^{4} + 4 x^{3} - 12 x^{2} + 5

arccos (\frac{2 x + 1}{x - 3})

f (x) = 7 - 6 x^{2}

f (x) = (x - 1)^{3}
