domain of f(x)=(x+2)/(x^2+1)

domain

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

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

y = - 2 tan (2 θ) + 1

f (x) = \frac{4 x - 5}{x + 6}

f (x) = \frac{2 x}{x ^{2}}

(\frac{5}{6})^{\frac{x ^{2} - 3 x}{x ^{2}}}

lo g_{10} (5 - 2 x)
