domain of ((y^2-3y-40))/((y^2+9+20))

domain

\frac{( y ^{2} - 3 y - 40 )}{( y ^{2} + 9 + 20 )}

- \infty < y < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < y < \infty

\frac{1}{8 x - 16}

f (x) = \frac{x}{4} - 1

y = x + 11 + 5

m c^{2}

y = 3 x^{2} - 6 x + 9
