domain of y=x^2+4x+2

domain

y = x^{2} + 4 x + 2

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

4 + \frac{5}{1 + x - 3}

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

f (x) = \frac{4 x}{x ^{2} + 16}

f (x) = \frac{x ^{2} + 3 x + 5}{x ^{2} - 4 x + 3}

ln (3 x - 2)
