Determine if the matrix below is invertible. use as few calculations as possible. justify your answer. [3 0 -4] [2 0 6] [-3 0 8]choose the correct answer below. (a) the matrix is invertible. the columns of the given matrix span r^3.(b) the matrix is not invertible. if the given matrix is a, the columns of a do not form a linearly independent set.(c) the matrix is invertible. the given matrix has 2 pivot positions.(d) the matrix is not invertible. if the given matrix is a, the equation ax = 0 has only the trivial solution.
