Answer:
Number of times = x
Cost = y
Step-by-step explanation:
The cost depends on the number of items. So the independent variable is item which is the x. The y is the cost since it is the dependent variable.
Hope it helps.

Data:
x: number of months
y: tree's height
Tipical grow: 0.22
Fifteen months into the observation, the tree was 20.5 feet tall: x=15 y=20.5ft (15,20.5)
In this case the slope (m) or rate of change is the tipical grow.
m=0.22
To find the line's slope-intercep equation you use the slope (m) and the given values of x and y (15 , 20.5) in the next formula to find the y-intercept (b):
Use the slope(m) and y-intercept (b) to write the equation:
A) This line's slope-intercept equation is: y=0.22x+17.2
B) To find the height of the tree after 29 months you substitute in the equation the x for 29 and evaluate to find the y:
Then, after 29 months the tree would be 23.58 feet in height
C) In this case as you have the height and need to find the number of moths you substitute the y for 29.96feet and solve the equation for x, as follow:
Then, after 58 months the tree would be 29.96feet tall

I am so sorry if it is wrong.... I tried
Answer:
D
Step-by-step explanation:
The range is the values of y covered by the graph
The graph on the left shows y going to - ∞
The graph has its maximum value at 4 ( turning point )
The range is therefore
- ∞ < y ≤ 4
