domain of cos(x^2-1)

domain

cos (x^{2} - 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) = 4 x^{2} + 3

f (x) = x^{4} + 4 x^{3} - 2 x^{2} - 12 x + 9

f (x) = \frac{7}{3 x + 11}

\frac{5 - x}{- 5 x}

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