Question

HELP MEDALS GIVEN
For the polynomial function ƒ(x) = x4 − 16x2, find the zeros. Then determine the multiplicity at each zero and state whether the graph displays the behavior of a touch or a cross at each intercept.
A.x = −4, cross; x = 0, touch; x = 4, touch
B.x = −4, touch; x = 0, cross; x = 4, touch
C.x = −4, touch; x = 0, cross; x = 4, cross
D,x = −4, cross; x = 0, touch; x = 4, cross

Answer 1

C i think.

Answer 2

how do you think ?

Answer 3

No it is D
i am positive

Answer 4

it is D

Answer 5

how did you get your answer ? @boxbennstrom

Answer 6

First, factor this: x^4 − 16x^2 = 0
