The domain of the function is the value of the independent variable, or simply the x-values. The range is the value of the dependent variable, or the y-values. You can determine its domain and range if the curve of the function passes through their coordinates. Hence, 

A. True. If you extend the curve downwards, its opening widens and would then encompass all x-values
B. True.
C. False. This is contradictory to A.
D. True. This is same with B.
E. False. This is contradictory to B.
F. False, the origin is at (0,2). It does not extend upward.

The answers are A, B and D.

True [87]

Kim's method of sampling the students in the given scenario is said to; It is not a random survey.

<h3>What is a random sample?</h3>

Random sampling is defined as a sampling technique whereby each sample has an equal probability of being chosen. This means that a sample chosen randomly is meant to be an unbiased representation of the total population.

In this question, we are told that Kim asked the first 50 kids to school in the morning about a question and used their responses to arrive at a conclusion.

Now, Kim's method is not random because it is biased as only those who came earliest were asked.

Jake tutors students. He charges $10 for the first session and $5 for each additional session. Let x
SIZIF [17.4K]

Answer: y = 5x + 10

Step-by-step explanation:

y= 5x + 10

THINK ABOUT IT! if 5 is for EACH additional session and x is equal to the NUMBER OF SESSIONS...... then 5 times x will give you the cost for each additional session, but NOT INCLUDING THE 10 FOR THE FIRST SESSION. so simply just do 5x + 10 and y is the total cost so

y = 5x + 10
