Question

Help with a problem? (Image)

Answer 1

substitute
x = 2 for ur equation

'cause
in ur equation
x = period and the period u want to find is 2 decades

\[f(x) = 2300 . \ 2^{x}\] \[f(x) = 2300 . \ 2^{2}\]\[f(x) = 2300 \times 4\]

got it :) ?

Answer 2

Not really. :(

Answer 3

the problem says that the equation gives the value of investment after x decades ....

Answer 4

so... if the equation is
f(x) = 2300 . 2^x
then the value of investment after 2 decades can be found by this...

since the amount u want to find is the value after 2 DECADES u have to find f(2)

and what i have done is finding f(2)

Answer 5

Would it be C then?
