Chelsea is graphing the function f(x) = 20(1/4)^x. she begins by plotting the initial value. which graph represents her first step?

C

Step-by-step explanation:

Point    (0,20)

Good luck

Refer the attached figure.

Step-by-step explanation:

Given : Chelsea is graphing the function .

She begins by plotting the initial value.

To find : Which graph represents her first step?

Solution : We have given the exponential function.

The form of exponential function is

Where,

a is the initial value

b is the base

x is the exponent

On comparing the given function with exponential function we get, a=20 the initial value.

or

The initial value is the value of the function when the value of x is equal to zero.

So, In the given function put x=0

The initial value is the point (0,20)

Now, we plot the graph which is the required result and represents her first step.

Refer the attached figure below.
