domain of (2x^2+4x+2)/(2x^2+2x+1)

domain

\frac{2 x ^{2} + 4 x + 2}{2 x ^{2} + 2 x + 1}

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

f (x) = 2 x^{2} - x + 1, (0 \leq x < 4)

\frac{7 x + 1}{8 - x}

y = \frac{cos ( x )}{x ^{2} - 5 x - 6}

x^{2} - 4 x, x < 5

f (x) = \frac{3 x ^{2} - 3 x - 6}{x ^{2} + 4 x + 4}
