domain of f(x)=(7+x)/(e^{cos(x))}

domain

f (x) = \frac{7 + x}{e ^{c o s (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

\frac{x ^{2}}{5 - x}

sin (x), - \frac{π}{2} < x < \frac{π}{2}

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

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

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