Answer:
Domain: all real numbers except x = 0 and x = -5.
Explanation:
You cannot have zero in the denominator. To find which values of x cause a zero in the denominator, set the denominator equal to zero, and solve for x.
x(x + 5) = 0
x = 0 or x + 5 = 0
x = 0 or x = -5
Domain: all real numbers except x = 0 and x = -5.
