The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input. The output values are y = 3, y = 3, y = 3, y = 5, y = 7. So we simply list these outputs without the "y=" portion. Toss out any duplicates. Only write the unique output values.
The curly braces surrounding the list of values tells us that we have a set.

For simple interest, it could be represented by a straight line
Answer:
area=144 ft²
Step-by-step explanation:
width=x
length=4x
perimeter=2(4x+x)
60=2(5x)
60/2=5x
30=5x
x=30/5
=6
width=6 ft
length= 4(6)
=24 ft
area= length * width
=6*24
=144 ft²
