domain of f(x)=2^{x+1}

domain

f (x) = 2^{x + 1}

- \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

\frac{3 x ^{2} - 18 x + 24}{x ^{2} - 4 x}

f (x) = 3^{x - 5} + 1

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

f (x) = \frac{( 10 x + 4 )}{( 8 x + 7 )}

y = e^{x}
