domain of f(x)=4(2^{-2x+7})-5

domain

f (x) = 4 (2^{- 2 x + 7}) - 5

- \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{1 - x}{x ^{2} - 1}

- x^{2} + x - 2

(\frac{1}{2})^{x} + 3

\frac{x - 3}{x ^{2}}

f (x) = \frac{3}{( x - 5 ) ^{2}}
