domain of f(x)=2pix^2+12pix

domain

f (x) = 2 \cdot π \cdot x^{2} + 12 \cdot π \cdot x

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

\frac{2 x}{x - 4} - \frac{x}{x + 5}

f (x) = \frac{2 x ^{2} - 4 x}{x - 2}

f (x) = \frac{9 - 4 x}{x - 4}

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