Given F(x,y,z): x*+ 3xy +2yz +y? +2z?-11 =0 defined around the point (x,y,z) = (1,2,0). b. Show that z = f(x,y) is an implicit function of x and y around the point (1,2,0). In other words, does it meet the conditions: i. Are all partial derivatives continuous. ii. IsF(1,2,0)=0 iii. Is F,(1,2,0)#0 c. Find % using the implicit function rule and evaluate it at (x,y,z) = (1,2,0). X d. Find %using the implicit function rule and evaluate it at (x,y,z) = (1,2,0)
