domain of f(x)=x^2+4x+3

domain

f (x) = x^{2} + 4 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

x^{2} + 5 x + 8

f (x) = x (x - 10 x)

- x^{3} + 3 x^{2} + 10 x

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

f (x) = a^{x}
