Answer:
- domain: (a) (-∞, ∞)
- range: (b) (-∞, 4]
Step-by-step explanation:
The domain is the horizontal extent of the graph. The arrows on the ends of the lines mean the graph extends indefinitely horizontally in both directions.
The range is the vertical extent of the graph. The arrows on the ends of the lines mean the graph extends indefinitely downward. The upward extent is marked by the turning points at y=4.
<h3>Domain</h3>
The horizontal extent of the graph is from negative infinity to positive infinity. Written in interval notation, this is ...
(-∞, ∞)
<h3>Range</h3>
The vertical extent of the graph is from negative infinity to +4. Written in interval notation, this is ...
(-∞, 4]
Answer:
14, 16, 18
Step-by-step explanation:
x + (x+2) + (x+4)= 48
3x + 6 = 48
3x = 42
x = 14
x+2 = 16
x+4 = 18
No, because it is not per second. You would have to simplify to per one second for it to be a unit rate. Hope it helps! :)

Answer:Y = 12
Step-by-step explanation:
Y varies ditectly as x
Y = kx
When y = -4, x = 2
Substitute the value of x and y into Y = kx
-4 = k * 2
Make k the subject of the formula
k = -4/2
k = -2
:. The equation connecting Y and x is
Y = -2x------
When x = -6
Y = -6*-2
Y = 12
