Answer:
Left side of graph of function would be up .
Step-by-step explanation:
Given : 
.
To find : In which direction does the left side of the graph of this function point.
Solution : We have given that .
We can see from the given function Degree is even and leading coefficient is positive .
By the behavior of end points : left side of graph would be up .
Therefore, left side of graph of function would be up .
C is the correct answer
dilation will change the shape and it will not be congruent
Answer: Using Chi-square.
Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.
If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.
However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.
