domain of f(x)=2x^2+8x+2

domain

f (x) = 2 x^{2} + 8 x + 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) = \frac{x - 5}{x - 11}

(4.2) (- 1.7)

\frac{x + 4}{x ^{3} - 4 x}

y = 1 - \frac{x}{6}

y = x^{2} + 4 x + 7
