domain of f(x)=1-2x^2

domain

f (x) = 1 - 2 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

y = sec (x)

y = \frac{1}{2} x - 3

x^{2} + 8 x + 14

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

x^{2} - 3 x + 3
