Answer:
domain: -2, -1, 0, 1, 2
range: 0, 2, -4, -8
Step-by-step explanation:
domain is the possible x values of the function. in this case, its a collection of plotted points, so we can just line up the x values of these points.
range is the possible y values of the function. again, we can just look at the y values of the points, line them up, and select our answer.
Based on the graph, the most profitable price to sell the video game is 45 dollars at which the profit is 34000 dollars. The worst possible price to sell the video game is 25 and 64 dollars.
A parabola is a U shaped curve that plots a quadratic equation. There are two types of parabolas- upward facing and downward facing.
In the given figure, a downward facing parabola is given. A downward facing parabola has a definite maximum value.
As we can see this maximum value occurs at a sales price of 45 dollars. Both above and below this price, the profit keeps on decreasing.
At 45 dollars, the predicted amount of profit (given on y axis) will be 34,000 dollars.
The 2 worst possible values to sell the video game at are 25 dollars and 64 dollars as in both of these prices, the profit is zero.

Answer:
The following lines is perpendicular, y=-x+6 and y=x+1
Step-by-step explanation:
- Slope of parallel lines are equal
(ex. slope of 2 stays 2 )
- Slope of perpendicular lines to another is the negative reciprocal
(ex. slope of 2 becomes -1/2)
y = -x + 6 and y = x + 1
the slope for y = -x + 6 is <em>-1 (-1/1)</em>
the slope for y = x + 1 is <em>1</em>
the slope -1 is the negative reciprocal of 1
hence, the definition of perpendicular fits the given

12/5
when you’re dividing by a fraction, you multiply by its reciprocal. 2 / 5/6 is the same as 2*6/5. 2*6 is 12, so your answer is 12/5
The answer would be 5 cuz 5 x 40 = 200
