Find all real zeros (if any) and state the multiplicity of each. at) = 43:5 322:" + 6433 z=|(0,4) x Enter a real zero, then a comma, and then its multiplicity. If the function has more than one real zero, enter a comma before the next zero. For example, if the function has the following zeros: 2 with multiplicity 1 3 with multiplicity 4 6 with multiplicity 2 then "(2.1), (-3.4), (6,2)" should be entered. The list can begin with any of the zeros. Enter "none" if the function has no real zeros
