Step-by-step explanation:
To identify the grpah correspondig to the given function find the zeros of the function (use the quadratic formula):
As the zeros are 2 and -6 the graph cross the x-axis in x=2 and x=-6
<h2>Answer: D</h2>
Answer: 3x -2
Because i know as soon as the line goes through the y-axis that number is your y-intersect and for the slope from the first point to the second point you go up 3 and over 1 and 3/1 is equal to 3 which gives your answer y=3x-2

Answer:
(B) Yes, there is reason. The TV audience might not be representative of the population.
(E) Yes, there is reason. Call-in polls tend to be biased.
Step-by-step explanation:
According to the information given we might consider two answers.
The first answer is:
<em>(B) Yes, there is reason. The TV audience might not be representative of the population.</em>
Let's remember that for a sample to be representative of a population must be random and every person must have the same probability of being selected. Here, the question is targeted only to the TV show's audience, so the results can only be interpreted for this segment of the population.
<em>(E) Yes, there is reason. Call-in polls tend to be biased.</em>
The risk is that the people who call might be influenced by the show itself and would not give an unbiased answer. This creates a bias on the sample. Besides, as stated before, not all the elements of the population can be part of the sample.
