Step 1 :The zeros of a polynomial function are the values of x that make the function equal to zero. In this case, the function is given in factored form, so the zeros are the values of x that make each factor equal to zero.
Step 2 :The function is \(f(x)=4(x-2)(x+8)^{3}\). The zeros are the values of x that make each factor equal to zero, so \(x-2=0\) and \(x+8=0\). Solving these equations gives \(x=2\) and \(x=-8\).
Step 3 :The multiplicity of a zero is the number of times that factor appears in the function. If a factor is raised to a power, that power is the multiplicity of the zero. The multiplicity of the zero \(x=2\) is 1, because the factor \((x-2)\) appears once. The multiplicity of the zero \(x=-8\) is 3, because the factor \((x+8)\) is raised to the power of 3.
Step 4 :The graph of the function crosses the x-axis at a zero if the multiplicity of that zero is odd, and touches the x-axis and turns around at a zero if the multiplicity of that zero is even. The graph of the function crosses the x-axis at \(x=2\) because the multiplicity of that zero is odd, and touches the x-axis and turns around at \(x=-8\) because the multiplicity of that zero is even.
Step 5 :\(\boxed{\text{Final Answer: The zeros are } x=2 \text{ and } x=-8. \text{ The multiplicity of the zero } x=2 \text{ is 1 and the multiplicity of the zero } x=-8 \text{ is 3. The graph of the function crosses the x-axis at } x=2 \text{ and touches the x-axis and turns around at } x=-8.}\)
