domain of f(x)=e^{-4t}

domain

f (x) = e^{- 4 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

y = x^{2} + 4

y = (x + 3)^{2}

(14, - 1.5), (16, 0)

f (x) = \frac{x - 8}{x - 2}

f (x) = \frac{x ^{3} + 8}{x ^{2} - x - 6}
