Determine whether the matrix is elementary. if it is, state the elementary row operation used to produce it. 1 0 0 0 −3 1 0 0 0 0 1 0 0 0 0 1 the matrix is elementary. it can be obtained from the identity matrix by interchanging two rows. the matrix is elementary. it can be obtained from the identity matrix by multiplying a row by a nonzero constant. the matrix is elementary. it can be obtained from the identity matrix by adding a multiple of a row to another row. the matrix is not elementary.

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.

true

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
