Question

Which Exponential function is represented by the graph?

A. f(x)=2(1/2)^x
B.f(x) =1/2 (2)^x
C.f(x)=1/2(1/2)^x
D.f(x)=2(2)^x

Answer 1

We will graph each case to determine the solution to the problem

using a graph tool

case a)
`f(x)=2( (1)/(2)^(x))`

see the attached figure N
`1`

case b)
`f(x)=(1)/(2) (2^(x) )`

see the attached figure N
`2`

case c)
`f(x)= (1)/(2) ((1)/(2)^(x))`

see the attached figure N
`3`

case d)
`f(x)=2 (2^(x))`

see the attached figure N
`4`

therefore

the answer is

case b)
`f(x)=(1)/(2) (2^(x) )`
