Question 8(Multiple Choice Worth 5 points) (08.06 LC)
Variable p is
more than variable d. Variable p is also 1 less than variable d. Which pair of equations best models the relationship between p and d?
Op= d+ 2
p=d-1
Op = 0 - 2
p=d+1
Od = 2p
d = 2p - 1
Od = 2p
d = 2p + 1

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
