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

domain

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

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

4 x - x^{2}

f (x) = 12 - 3 x

f (x) = \frac{2 x + 1}{3 x - 2}

f (x) = \frac{3 x}{x ^{2} - 20 x + 12}

y - 7 = - 3 (x + 5)
