domain of f(x)=((x^2-1))/((x^2+4))

domain

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

- \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

h (x) = 3 (x - 4)^{2} - 8

f (x) = \frac{7}{2} (3)^{x + 1} + 2

f (x) = 2 π x^{2} + 8 π x

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

3 x^{3} - 8
