Which is the graph of f(x)=4(1/2)^x

 The sketching method of the given graph is shown in the below explanation.

Step-by-step explanation:

Given function,  -------(1)

Since it is an exponential function.( because it is the type of )

here, the horizontal asymptote, y=0

And, it having x intercept (0,4)

But it does not have any y- intercept.

Also, it is a decreasing function because here b<1.

Now, we can draw it with help of putting some values of x in equation (1)

For x= 1, y= 2 and x=2, y=1

for x=-1, y=8  and, x=-2, y= 16

Thus points are (1,2), (2,1), (-1,8) and (-2,16).  

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
