Given the graph of the function f below, estimate the intervals in which fis increasing.

nadezda [96]

Answer:

(-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

"Increasing" means the graph goes up to the right. It is increasing from the left up to the local maximum--the peak at left.

It is increasing again from the local minimum on the right to the right side of the graph.

The two sections where the graph is increasing are ...

(-∞, -5/2) ∪ (1, ∞)

The graph is decreasing between the maximum on the left and the minimum on the right.

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

$-20x^2 -50x + 200 = 30x-10$

=> $20x^2 +20 -210 = 0$

Using the quadratic formula to solve this equation we have that

x = $2.779
