Solve this system of equations using a matrix inverse. If A is the coefficient matrix of the above system of equations and , then the elements of are , the elements of are , and the elements are . The solution of this system is (x, y, z) = .

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.
