ow that it is increasing at a decreasing rate. Mathematically, U'(W)>0 and U
''(
W)<0. Also graph each function to verify your results.
Exponential U(W)=e^(-AW)
Logarithmic U(W)=ln(W)
Quadratic U(W)=W-0.5AW^2
Power U(W)=(B/(B-1))*W^(1-1/B)
Describe a risk averse, a risk seeking and risk neutral investor.
what shape would the utility function of each be in risk-return space?
