Answer: 2,1 4,1 5,7 and yeah im not sure what else to put
poggers hehe
Hello!
A cubic function is in the form of 
.
All cubic functions have a domain of all real numbers, the range also has a range of all real numbers.
Interval notation is used for representing a function/interval as a pair of numbers. Parentheses and brackets are used to show if the endpoints of a given function/interval are included or excluded. Brackets allow the endpoints to be included while parentheses exclude the endpoint.
Our first instinct would be that the domain is written as [-∞, ∞], but that is incorrect. Infinity is not a number, but it is a concept. This means that they are excluded from the domain.
Therefore, the domain of the function f(x) is (-∞, ∞).

Yes the person is right I was trying to type it but they beat me to it
Answer:
Step-by-step explanation:
Correlation measures the strength of the linear relationship between two variables.
A linear relationship exists between two variables if one variable increases as the other increases or decreases.
Use the formula for correlation coefficient to determine the strength of the relationship.
Correlation coefficient, r is equal to the sum of squares of xy divided by the product of the square root of the sum of squares of xx and xy.
The sample correlation coefficient r measures the strength of the linear relationship and has the following properties:
-1≤r≤1; the closer the value is to −1 or 1, the stronger the linear relationship
– If r is negative, this indicates that as one variable is increasing, the other is decreasing
– If r is positive, this indicates that both variables are increasing or both variables are decreasing
If r = 0, then there is no linear relationship between the two variables
