The equation f=v + at represents the final velocity of an
object, f, with an initial velocity, V, and an acceleration rate,
a, over time, t.

Find the directions in which the function increases and decreases most rapidly at upper p 0p0. then find the derivatives of the function in these directions. f(x,y)equals=x squared plus xy plus y squaredx2+xy+y2, upper p 0p0left parenthesis 1 comma negative 4 right parenthesis
