domain of f(x)=2(x+1)

domain

f (x) = 2 (x + 1)

- \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

x^{2} - 7

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

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

9 x + 3 y = 3

5 x - 1
