Will give Brainliest! Please answer!! 1.) Find the unit vector in the direction v = -3i + 2j and write your answer as a linear combination of the standard unit vectors i and j.

2.) Find uv if u = 3i + 4j and v = 5i + 2j.

Which function has an inverse that is also a function? a.{(-4,3), (-2, 7), (-1,0), (4, -3), (11, -7)} b.{(-4, 6), (-2, 2), (-1, 6), (4,2), (11, 2)} c.{(-4,5), (-2, 9), (-1,8), (4, 8), (11,4)} d.{(-4,4), (-2, -1), (-1,0), (4, 1), (11, 1)}
