Which graph shows an increasing exponential function with a y-intercept of 4?
2 answers:
Answer: Well, you never actually included any instruction, but, i'm gonna say it is the top right graph.
Step-by-step explanation:
You can deduce that the bottom two are not as the bottom right is going at a consistent rate which makes it linear, the bottom left would be the case if it was an x-intercept of 4. The top left graph is going into the negative x-axis meaning that as x were decreasing, y would be increasing and it is asking for an entire exponential function so you are left with the top right which is in the positive x and y axis and intercepts the y-axis at 4.

Let the dimension be x and y.
So, the perimeter is given as:
Because it has one additional fence, the perimeter is calculated as:
Make y the subject
The area is calculated as:
Substitute
Expand
Differentiate
Set to 0
Rewrite as:
Divide both sides by 4
Substitute 90 for x in
Hence, the maximum area is 16200 square yards
