Final answer:
The zeros of the given polynomial function are x = 0, x = 9, and x = 5/4 with a multiplicity of 1.
Step-by-step explanation:
The given polynomial function is g(x) = 12x(x - 9)(4x - 5). To identify the zeros of the function, we set g(x) = 0 and solve for x.
Setting each factor equal to zero, we have:
12x = 0 -> x = 0
x - 9 = 0 -> x = 9
4x - 5 = 0 -> x = 5/4
So, the zeros of the function are x = 0, x = 9, and x = 5/4.
The multiplicity of each zero is 1 because each factor is linear and appears only once.
