perimeter=(L+W)2

L=x^2+2x-3

W=2x^2+3x+5

(x^2+2x-3+2x^2+3x+5)2

Question 1-3
Vikki [24]

The production graph of the company is a quadratic graph

The true statements about the production graph are:

  • When producing 5,000 sets of headphones per week, the weekly earnings is $0.
  • Producing 2,500 sets of headphones per week will give the maximum amount of weekly earnings.
  • The maximum possible earnings is about $6,250 per week.
  • If production is increased from 1,500 to 2,000 sets of headphones per week, then the weekly earnings will also increase

<h3>How to interpret the model?</h3>

To interpret the model, we simply evaluate the options one after the other

<u>Producing 5000 sets weekly</u>

From the graph, we have:

(x,y) = (5000,0)

This means that a weekly production of 5,000 sets of headphones give an earning of $0.

Hence, this option is true

<u>Increased production from 3000 to 4000</u>

From the graph, the function value decreases when x increases from 3000 to 4000.

This means that this option is false

<u>Producing 2500 sets</u>

The production of 2500 sets give a maximum earning of $6250

This means that options (c) and (d) are true

<u>Increased production from 1500 to 2000</u>

From the graph, the function value increases when x increases from 1500 to 2000.

This means that this option is true

Hence, the true statements are: (a), (c), (d) and (e)
