domain of 1/2 (x+3)

domain

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

- \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

y = x^{2} + 5

y = x^{2} + 7

x^{2} - 8 x + 15

f (x) = \frac{1}{x ^{2} + 3 x - 4}

f (x) = \frac{x}{1 - x}
