The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.
lisov135 [29]

Answer:

The  price is   x =  $2.779

Step-by-step explanation:

From the question we are told that

  The  revenue is  y = - 20x^2  - 50 x + 200

   The cost of production is  y = 30 x - 10

Generally at break even point the cost of production is equal to the  revenue

So

      -20x^2 -50x + 200 =  30x-10

=>   20x^2 +20 -210 = 0

Using the quadratic formula to solve this equation we have that

       x =  $2.779

Compare the functions shown below:
emmasim [6.3K]
The intersection with the y axis occurs when x = 0.
 We have then:
 
 For f (x):
 
f (0) = -3 (0) - 5

f (0) = 0 - 5

f (0) = - 5

 For g (x):
 
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3

 For h (x):
 
h (0) = 2cos (2 (0) -\pi) +4

h (0) = 2cos (0-\pi) +4

h (0) = 2cos (-\pi) +4
 h (0) = 2 (-1) +4

h (0) = -2 + 4

h (0) = 2

 Therefore, the graph with the intersection with the largest y axis is h (x)

 Answer:
 
the greatest y-intercept is for:
