Please help me find the domain.
State the domain:
f(x) = (2x^2 - 9)/ (x^3 - 16x)
-----
The denominator cannot be zero:
Solve: x^3-16x = 0
x(x^2-16) = 0
x(x-4)(x+4) = 0
x = 0, 4, or -4
======================
Domain: All Real Numbers except x = -4, or x = 0, or x = 4
===============================================================
