domain of f(x)=-x^6+7x^2+9x+12

domain

f (x) = - x^{6} + 7 x^{2} + 9 x + 12

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

(x - 1)^{2} - 4

f (x) = \frac{5}{x - 7}

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

f (x) = \frac{1}{x - 12}

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