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

domain

f (x) = 4 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) = \frac{x}{x ^{2} - 64}

f (x) = (x - 2)^{2} - 1

(3 x - 4) - (2 - x)

x^{2} - 3 x + 2

f (x) = lo g_{10} (x - 1)
