I need help with this problem please and please make it legible.

legible. By about how much will f(x,y,z) = In 4x2 + y2

By about how much will f(x,y,z) = In 4x2 + y2 + 22 change if the point P(x,y,z) moves from Po(4,3,9) a distance of ds = 0.1 unit in the direction of 3i + 6] - 2k? m The change in value is about df z :|. (Round to four decimal places.)
