What is the greatest common factor of 2 16 and 12

Step-by-step explanation:

The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
