The missing options are:
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
D. In the xy plane, point (5,000,20) is on the graph y = f(x)
Answer:
C. In the xy plane, point (20, 5,000) is on the graph y = f(x).
Step-by-step explanation:
Given
Represent amount with y and weeks with x
So, we have:
x = 20 when y = 5000
Required
Select 2 correct options
A point on a graph can be illustrated using
So, when x = 20 and y = 5000 ----- given
implies that:
We got by substituting 20 for x and 5000 for y

<em>From the list of given options, the above represented of (x,y) is illustrated in option C</em>
Represent (x,y) as a function, we have:
Substitute values for x and y
