domain of y=3x^2-18x+30

domain

y = 3 x^{2} - 18 x + 30

- \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

- e^{x}

- \frac{21}{( 4 + x ) ^{2}}

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

y = x^{2} + 5

y = x^{2} + 7
