domain of x^2+3x+1

domain

x^{2} + 3 x + 1

- \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) = 3 + 4 x^{2} - \frac{1}{2} x^{4}

f (x) = x^{3} - 1

x - 2 y = 2

y = 2 x + 7

f (x) = y^{2}
