domain of f(x)=7x^2+9

domain

f (x) = 7 x^{2} + 9

- \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) = 3^{x} + 2

m = \frac{8}{3}, (13, 5)

f (x) = x^{3} - 11 x^{2} + 24 x

\frac{x}{6 x + 25}

f (x) = \frac{( x - 6 )}{x + 6}
