Three points are graphed on the coordinate plane. Dave must find a fourth point so that the four points will form a parallelogram. Find all 3 possibilities for the fourth point. Drag and drop the numbers into the ordered pairs. I'm so so confused. Can somebody please please help? I put the drag and drop numbers as the second picture.

If f(x)=2x+2and g(x)=x^3, what is (g•f)(2)
