Could you please help me to solve this and explain what the "multiplicities" are. I am having trouble understanding this. Thank you.

L` 9 - 0 2 ) Use the function f ( x ) = - 4x (* - 6 ) ( x 2 - 16) to determine the following : 05/4, 6 2 ) Find the zeros of f . X b ) Sketch a graph of { that's " good enough " to show the four* zeros of the function , their multiplicities , and the end behavior of the function .
