Answer:
A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. The most common symbol for the input is x, and the most common symbol for the output is y; the function itself is commonly written .
Step-by-step explanation:
If it were 100 it would be $20, so for 1000 you just add one more zero and it’s $200
The answer is non-linear and increasing. hope this helps
The formula for the average rate of change is given as:
From the interval provided, take
Comparing on the graph,
Inputting the values into the equation for average rate of change,
Therefore, the average rate of change for the interval -9 ≤ x ≤ -8 is 60.
