domain of f(x)=2x^2-12x+18

domain

f (x) = 2 x^{2} - 12 x + 18

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

f (x) = - 3 x^{2} + 4 x - 3

\frac{x ^{2} - 81}{x ^{3} + 7 x ^{2} - 18 x}

f (x) = 2 - x + 4

e^{x} + 4

y = 2 x + 2
