I have been having major issues trying to figure this out...can someone please try and explain to me?
F(20) = 40e ^0.032(20) = ~ 75.9

Best ResponseYou've already chosen the best response.0are you confused as to how the left hand side is equal to the right hand side?\[40e ^{0.032(20)} \approx 75.9\]

Best ResponseYou've already chosen the best response.0OK, I saw from your previous posting that you don't understand how the left hand side is equal to the right hand side.

Best ResponseYou've already chosen the best response.0\[\begin{align} 40e^{0.032(20)}&=40*e^{0.032*20}\\ &=40*e^{0.64}\\ &=40*1.8965...\\ &=75.859...\\ &\approx75.9 \end{align}\]hope that helps...

Best ResponseYou've already chosen the best response.0so I ignore the f(20)?

Best ResponseYou've already chosen the best response.0My guess is that you were given a function of the form:\[f(x)=40e^{0.032x}\]and were asked to evaluate the function at \(x=20\) so that you would then get:\[f(20)=40e^{0.032(20)}\]

Best ResponseYou've already chosen the best response.0you made a mistake there. it is not 2.718*0.64 but \(2.718^{0.64}\)

asnaseer

Best ResponseYou've already chosen the best response.0i.e. 2.718 to the power of 0.64

Best ResponseYou've already chosen the best response.0don't worry too much if you don't grasp things too quickly. as long as you keep practicing, you will slowly begin to master this subject.
