Solution
To demonstrate that the function is a linear mapping between real vector spaces, we need to verify two properties of linearity for :
- Additivity:
- Homogeneity: , where is a scalar.
Given:
- The function is defined by , where .
Step 1: Check Additivity
For functions : Using the properties of derivatives and addition in functions: Thus, additivity is satisfied: .
Step 2: Check Homogeneity
For a scalar and a function : Using the derivative property of scalar multiples: Thus, homogeneity is satisfied: .
Conclusion
Since satisfies both additivity and homogeneity, is indeed a linear mapping.
