Which exponential function is represented by the graph? O f(x) = 2( 1/2 )x
O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!

f(x) =

Step-by-step explanation:

Using the standard form of the exponential function

y = a

To find a and b , substitute ordered pairs from the graph

Using (0, 0.5 ), then

0.5 = a [

a = 0.5 , so

y =

Using (1, 1) , then

1 = , thus

b = 2

f(x) = ← exponential function representing graph
