Answer:
Step-by-step explanation:
The range of a function is the set of all possible values it can produce.
For example, consider the function

No matter what value we give to x, the function is always positive:
If x is 2, then the function returns x squared or 4.
If x is negative 2, then it still produces 4 since -2 times -2 is positive 4.
So the range of the function is
"all real numbers greater than or equal to zero".

A
Step-by-step explanation:
A customer that uses an internet plan that costs $10 per month is expected to give a customer rating of 6
<h3>How to determine the customer rating?</h3>
We start by calculating the regression equation of the table of values using a graphing calculator.
Using the graphing calculator, we have:
y = 0.04x + 5.75
When the cost is $10 per month, it means that
x = 10
So, we have:
y = 0.04 * 10 + 5.75
Evaluate
y = 6.15
Approximate
y = 6
Hence, a customer that uses an internet plan that costs $10 per month is expected to give a customer rating of 6

Answer:
independent quantitative.
Step-by-step explanation:
An indepentent variable in an investigation, is the variable that will be changed in order to know how its variation affects the dependent variable.
