J represents a 3x2 matrix and H represents and 2x4 matrix.y= Hxandz= Jy, whereyis a 2x1 matrix,zis a 3x1 matrix, andxis a 4x1 matrix. Form the composition J○H and simplifyz= J○Hx.

3. The attempt at a solution

I don't know what my answer is going to look like because I don't know what a composition of matrices represents. Is it the same as matrix multiplication?
