domain of 3x^2-x

domain

3 x^{2} - 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 x - 10 )}{( x ^{2} - 8 x + 15 )}

3 x^{2} - 4

20 t - 5 t^{2}

- 7 x + 8

f (x) = - x + 16
