Answer:
Step-by-step explanation:
1)
y is 3 times more than x.
X=0 Y=0 3x0=0
X=1 Y=3
X=2 Y=6
X=3 Y=9
X=4 Y=12
Then just plot it as co-ordinates (x,y)
2)
Y is 1/4 of x. Divide by 4
X=0 Y=0
X=4 Y=1
X=8 Y=2
X=12 Y=3
X=16 Y=4
Then just plot it as co-ordinates (x,y)
As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research.
✿ Domain is the Set of Values of x
⇒ Domain = { 10 , 15 , 19 , 32 }
✿ Range is the Set of Values of y (Images of x)
⇒ Range = { -1 , 5 , 9 }
First Option is the Answer
That would be a variable, x being one of the most commonly used variables to represent unknown numbers.
