I need good explanation this question.

So the answers to the quartic equation would be x=3, x=3, x= -2 + √3, and x = -2 - √3

work backwards,

e.g. if you had a quadratic function whose zeros are 3 and -4, wouldn't you have two factors, namely

(x-3) and (x+4), and your equation would have to be y = a(x-3)(x+4) , where is a non-zero constant

which would have no effect on the solution.

so form the 4 factors from the given zeros, (yes , two of them are the same)

and y = a(...)(...)(...)(...)

answer:

c. the third graph

d
