2. Which equation best defines the function on the graph?
y
1 2 3 4 5
-2
A y = -x + 2
B y = \x+21
Cy=-\x1 +2
Dy = |-x] +2

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
