anonymous · Answer

Do you know the general form of the exponential function you dealing with?

anonymous · Answer

No, I don't know where to start.

anonymous · Answer

you have not dealt with any exponential functions at all?

anonymous · Answer

I know that the function is in the form of c multiplied to a to the power of x.

anonymous · Answer

ok can you write that in the mathematical form?

anonymous · Answer

hello?!

alekos · Answer

equation should be of the form  y=Ae^-kx

then we get two solutions

1:   400 = Ae^-k
2:    25  = Ae^-5k

From here you can solve A and k

anonymous · Answer

no that only natural logarithmic function @alekos 

her function would be of form $$y = c \times a^x$$

alekos · Answer

if you wish to go that way it will be......

y = Ca^(kx)

you can do this two ways
