domain of f(x)=7x+2

domain

f (x) = 7 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

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

f (x) = x^{3} - 2 x^{2} + 5 x + 7

f (x) = - 3 x - 17

y = \frac{2}{\frac{7}{x + 1} + 3}

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