To find the growth rate of B, $$\frac{ intiial value-nextdayvalue }{ initialvalue }$$$$\frac{ 22-21.56 }{ 22 }=.02$$Change the decimal to a percent by moving the decimal place to the right two places. So you have growth rate of 2%.

However, the stock is losing value each day, so the growth rate is negative. So you have a negative 2% growth rate. So instead of adding the growth rate to 1, you have to subtract the growth rate (1-.02=.98)

The equation would be $$f(x)=22(.98)^{x}$$ 

For part D you have two columns, I don't where the values in the second column are coming from so I'm much help there.
