domain of f(x)=x^4-8x^2+12

domain

f (x) = x^{4} - 8 x^{2} + 12

- \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 = 16 ln (9 x - 7)

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

f (x) = 2 x + 1 + 2 - x

f (x) = \frac{2 x - 7}{2 x}

y = 3 + x
