I think it should be option d
Answer:
- D. It is a many-to-one function
Step-by-step explanation:
- One-t<em>o-one if every y value has exactly one x value mapped onto it</em>
- <em>Many-to-one if there are y values that have more than one x value mapped onto them.</em>
We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function
Correct option is D

Step-by-step explanation:
A goes between -1 and -1/2
Answer: (B)
Step-by-step explanation:
An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.
The independent sample test would be the best hypothesis test for this study because:
1. There was a random samples of data from the population
2. There was no relationship between the subjects in each sample. That is;
- subjects in the first group were not also in the second group
- subjects in the first group did not influence subjects in the second group and vice versa.
3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.
4. There are values on both the dependent and independent variables.
- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.
5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.
6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.
