Use the Leading Coefficient Test to determine the end behavior of the polynomial function. Then use this end behavior to match the function with its graph.f(x) = 4×2 – 3x – 1

Find the zeros of the polynomial function.

Write the declaration for class D , which is derived from class B in the former question . The class’s membersshould be:• q , a float . This variable should not be accessible to code outside the class but   should be accessible to member functions in any class derived from class D .• r , a float . This variable should not be accessible to code outside the class, but   should be accessible to member functions in any class derived from class D .• setQ , getQ , setR , and getR . These are the set and get functions for the member   variables q and r . These functions should be accessible to code outside the class.• calc , a public member function that overrides the base class calc function. This   function should return the value of q times r .

Suppose you know that increased screen time leads to less sleep. You collect data on exam scores and screen time and fit the following simple linear regression:     Answer the following (3 points) If you had data collected on your hours slept before an exam and your exam score and were to fit it to a similar simple linear regression model (exam_score ~ hours_slept), what would you expect the sign of the slope to be?. (3 points) Would you expect the linear model to be statistically significant? Why? Which column of the OLS output would you check? (4 points) Would you expect the R2 value for exam_score ~ hours slept to be higher or lower than the one for exam_score ~ screen_time? Explain your reasoning

This is a bonus question worth 0.5 points if correct.    In pediatric depression, irritability or anger may be more prominent than overt sadness.

You are examining the apparent relationship between two variables, displacement  and weight  from the Auto dataset of Module 2. Below is a plot of px.scatter(x=df.displacement, y=df.weight, width=400)The histograms of the two variables are below:You run a test for correlation using Pearson’s R and obtain the following results:Pearson’s R: 9.3310e-01P-value: 1.5300e-177  (3 points) List the null and alternative hypothesis (5 points) Interpret the results and describe any potential issues with this analysis.
