domain of f(x)=-2x^2+16x-31

domain

f (x) = - 2 x^{2} + 16 x - 31

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

f (x) = \frac{x + 4}{2 - x}

3 - x - 2 + x

f (x) = \frac{4 x ^{2} - 1}{2 x + 1}

f (x) = 15

f (x) = \frac{1}{x} y g (x) = \frac{1}{x ^{2}}
