domain of y=(x-1)/2

domain

y = \frac{x - 1}{2}

- \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) = 3^{x} - 9

y = x - 3, (3, - 2)

f (x) = x^{3} - x

f (x) = 5 - x

5 e^{- (x + 1)^{2}}
