Answer:
B. f(x)
D. h(x)
Step-by-step explanation:
An exponential function will have a common ratio.
We check and see if the consecutive terms has a common ratio.
For f(x),
This is not an exponential sequence.
For g(x), we have:
For h(x),
This is not an exponential sequence
For k(x),
<u>Answer-</u>
<em>The maximum area that they can fence off is</em><em> 6400 ft²</em>
<u>Solution-</u>
Organizers of an outdoor concert will use 320 feet of fencing to fence off a rectangular vip section.
i.e the perimeter of the rectangular section is 320 feet
Let us assume,
x = length of the rectangular section
y = breadth of the rectangular section
Hence,
Now, we have to find the maximum area for which they can fence that off.
The area of the rectangular section is,
So we have to maximize the area function.
Putting the value of y,
Finding the critical values,
∵ f"(x) is negative (i.e -2), so for the value of x=80, f(x) or area function will be maximum.
Therefore, the maximum area that they can fence off is 6400 ft²
