Consider the solid that lies above the square (in the xy-plane) r=[0,1]×[0,1] and below the elliptic paraboloid z=36−x2+2xy−y2. estimate the volume by dividing r into 9 equal squares and choosing the sample points to lie in the midpoints of each square.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
