domain of x^2+x+x^2-7

domain

x^{2} + x + x^{2} - 7

- \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{3 x + 1}{6 x + 2}

f (x) = \frac{1}{3 x - 9}

f (x) = x + 1.5

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

f (x) = 16 - x^{2}
