Given that the values in the table represent the graph of a continuous function, y has at least how many zeros? !

For this case, since the function is continuous, what you should do is see the sign changes.
 We have the following sign changes:
 x         y
 -2.4    0.69
 -1.8   -0.39
 -1.2    0.24
   0      0
   0.6  -0.46
   1.2  -0.24
   1.8   0.39
   2.4  -0.69
 Therefore, the number of zeros is:
 5
 
 5

Iwould say d but i am not 100% positive
