Assuming that the function  f  has continuous second partial derivatives  and that  a  and  b  are constants,  calculate and simplify    +   f(ax + by, bx - ay).
◦ (a2 + b2) f11(ax + by, bx - ay) +  f22(ax + by, bx - ay)
◦ a2f11(ax + by, bx - ay) +  b2f22(ax + by, bx - ay)
◦ (a2 + b2) f11(ax + by, bx - ay) -  f22(ax + by, bx - ay)
◦ (a2 - b2) f11(ax + by, bx - ay) -  f22(ax + by, bx - ay)
◦ (a2 - b2) f11(ax + by, bx - ay) +  f22(ax + by, bx - ay)
