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
Reorder

The above is illustrated in option A
<em>Hence, A and C answers the question</em>
the coordinates where the bridges must be built is and
.
<u>Step-by-step explanation:</u>
Here we have , a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream at point A and then again at point B. Bridges must be built at those points.We need to find Identify the coordinates where the bridges must be built. Let's find out:
Basically we need to find values of x for which f(x) = g(x) :
⇒
⇒
⇒
⇒
⇒
⇒
⇒
⇒
⇒
Value of g(x) at x = 3 : y=3x -15 = 3(3)-15 = -6
Value of g(x) at x = 6 : y=3x -15 = 3(6)-15 = 3
Therefore , the coordinates where the bridges must be built is and
