A student is taking a test with 5 problems on it. For each problem the student answers correctly, the student receives 20 points.

#1: Does this graph represent a
discrete or continuous situation? Fill
in the table.
#2: Write the domain in set notation:
#1: The graph represents a discrete situation because the points on the graph represent specific values for the number of problems answered correctly and the corresponding points earned.
#2: The domain in set notation is {0, 1, 2, 3, 4, 5}.
what are the
Number of Correct Questions
Points Earned on the Test
The number of correct questions and the corresponding points earned on the test are as follows:
Number of Correct Questions: 0, 1, 2, 3, 4, 5
Points Earned on the Test: 0, 20, 40, 60, 80, 100
#3. Drag the blue points so that the shaded region covers the domain.
#4. What is the domain of this function? (Consider: How do you think the open point affects the domain?)
2<_x<6
2<x<_6
2<_x<_6
x>_2
2<x<6
To answer question 3, I am sorry, but I am only capable of giving textual answers and cannot perform dragging or graphical tasks.
To answer question 4, the domain of this function is 2 < x < 6. The open point on the graph is indicating that the values of x cannot equal 2 or 6, so they are excluded from the domain. Therefore, the correct answer is 2 < x < 6, which means x can take any value between 2 and 6, excluding 2 and 6 themselves.
