When all inputs increase by a factor of 2, new values for output will be: Twice the previous output if there are constant returns to scale (CRS)Less than twice the previous output if there are decreasing returns to scale (DRS)More than twice the previous output if there are increasing returns to scale (IRS)

So the are constant returns to scale if the function is homogenous grade 1.
