domain of f(x)=4-2e^x

domain

f (x) = 4 - 2 e^{x}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

f (x) = \frac{x - 2}{x ^{2} + 4 x - 21}

f (x) = 3 cos (x) + 1

y = 5 x + 50

f (x) = \frac{x}{x - 4}

f (x) = x^{2} - 6 x - 7 + 5 - 2 x
