The answer is C.
Set each factor of the formula of the function equal to 0 and solve for x in order to find the x-intercepts:
x + 3 = 0 then x = - 3;
x - 3 = 0 then x = 3;
x - 4 =0 then x = 4.
Therefore, the graph of the function has x-intercepts - 3, 3 and 4.

What if i jumble the terms and write them as y=(x-3)(x+3)(x-4), Then?? There is no difference...between the two functions...so, now?

Yes, you are right. I didn't see the negative sign of - 4 in the option A), it is pretty small hehehehe. So the only correct option is C).

A has the same solutions...Why not A??

Because the zeros in A) are not in ascending order. That's why I would select C) as my answer.

Thank you! I tried A the first time I took the test and got it wrong so I was pretty sure it had to be C but I thought double check! :)

Note that though the graph is the same, the answer to the second question of "What are the zeros of the function" are different.

Answers in A are $3, -3, -4$, answers in C are $-3, 3, 4$.

The answer could be both A and C...i am not able to see a difference between them!!

Only (c) can be the correct answer... As zeroes of the function suggest
