Given the two vectors a = (-1,-2,1) and b = (3,-2,4), does the vector =(-9,-2,1) lie on the plane determined (spanned) by a and b? Explain.

Take this test to review the material in Chapters 4and Chapters 5. After you are finished, check your work against the answers in the back of the book. Write w=(7,2,4) as a linear combination of the vectors v1, v2 and v3 if possible. v1=(2,1,0), v2=(1,1,0), v3=(0,0,6)
