How many real numbers are not in the domain of the function f(x) = (1/x-64) + (1/x^2 - 64) + (1/x^3 - 64)
+23246 If the function is: f(x) = 1 / (x - 64) + 1 / (x2 - 64) + 1 / (x3 - 64)
The real solution of x - 64 is 64
The real solutions of x2 - 64 are 8 and -8
The real solution of x3 - 64 is 4 (there are also two complex solutions)
Thus, there are 4 real numbers not in the domain of this function.
