Question

Which function could produce the graph shown below?

a. f(x)=4e^0.5x
b. f(x)=4e^-0.5x
c. f(x)=4e^0.05x
d. f(x)=4e^-0.05x

Answer 1

it is decay so forget A and C

Answer 2

lets try B
\[4e^{0.5}x\] if \(x=3\) you get
\[4e^{1.5}=.892\] which looks about right

Answer 3

for D if \(x=3\) you get
\[4e^{-.15}=3.44\] so it is not that one

Answer 4

so b then? :)
