Domain:
From left-to-right, the graph starts at x = -4 and goes on forever to the right.
The domain is x ≥ -4.
Range:
From bottom-to-top, the graph gets as low as y = 1 and goes up forever.
The range is y ≥ 1.
"Common" means "same for both" or "same for all".
There's nothing common about a single item. There's no such thing
as a "common"factor unless there are at least two numbers.
Vertex is -b/2a. The variable b=2 and a=2. That finds the x coordinate of the vertex. Then to find the y coordinate you just plug the number you got for x (-1/2) into the equation. Like so:
y = 2x+2
y = 2(-1/2)+2
y = -1+2
y = 1
So your vertex is ( -1/2, 1 )
To graph your vertex you take your x coordinate (-1/2) and find it on the x axis of the graph (horizontal line). Then do the same for y (1) (on the vertical axis.
Now that you have your vertex graphed you can find out if it is minimum or maximum by looking at the direction in which the slope is going. If it goes in the positive direction (up) then it is a minimum since that is the lowest point that the line touches. If it is maximum it is opposite. The line faces down and the highest point the line touches is that point.
Answer: Rs 280
A dozen = 12
12 notebooks --> Rs 480
1 notebooks --> 480/12 =Rs 40
7 notebooks --> 40 * 7 = Rs 280
Answer:
-$3800
Step-by-step explanation:
Javier lost $19 on each of his 200 shares, so his total loss was ...
... 200 shares × $19/share = $3800
The portfolio lost $3800 in value on Tuesday.
