please answer them correctly and show all work

4. Based on the answers to the above questions, sketch the radial wavefunctions for the 4s and 3d orbitals. "Sketching" only requires the right number of nodes (places where R(r)=0 ) and the right sign of the function between nodes or between the origin and nodes. Actual numerical values are not important. 3. Please sketch the functions R2(r) and 4[r2R2(r) for R4,0 (Please indicate number of nodes and relative magnitude, no exact numbers are needed)
