domain of-x^2+2x+3

domain

- x^{2} + 2 x + 3

- \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

f (x) = lo g_{5} (x^{2} + 1)

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

+ arcsin (2 x)

6 x + 7

y = 20 t - 5 t^{2}
