Y2 = Y1
Y2 > zY1
Y2 < zY1
Y2 = zY1 (correct)

If the inputs K1 and L1 are increased by 25%, what happens to the output Y2?

Y2 > 1.25Y1
Y2 = Y1
Y2 = 1.25Y1 (correct)
Y2 < 1.25Y1

If the output Y2 is greater than zY1, what can be inferred about the returns to scale?

Decreasing returns to scale
Constant returns to scale
No relationship can be inferred
