domain of f(x)=x+3

domain

f (x) = 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 = 4 x - 4

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

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

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

f (x) = \frac{( x + 8 )}{( x ^{2} + 7 x )}
