Question

which of the following is the exponential function y=Ce^kx that passes through (1,e)and (2,e^2)
a)y=e^2x
b)y=2e^x
c)y=e^x
d)y=ee^e^2x
e)none

loser66 · Answer

to me, I plug (1,e) into the function y = C e^kx to have 1st equaion
and then plug (2, e^2) into it again to have 2nd equation
from those I solve for C and k, to get the answer. I got my own answer, hopefully, you can do it. follow my way. Try , please. and then we compare our solution
