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

domain

f (x) = e^{- 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

x^{2} - 8 x + 12

x^{2} + 10 x + 25

(0, 3), (3, 0)

f (x) = \frac{2 x}{x + 7}

f (x) = 8 x^{2}
