Answer:
See Below
Step-by-step explanation:
The boundary line follows the graph of y = 2x - 4 because it represents the line of maximum or minimum values the graph could take. y = 2x - 4 has a y-intercept of -4 because it is in slope-intercept form. It also has a slope of 2, so to find another point on the line, you can go up two and right one. Also, this inequality has a solid line because it is "less than or equal to" and a solid line represents the values that equal.
Student 4 has the largest percent error.
Step-by-step explanation:
The percent error of a measurement is given by
where
x is the value of the measurement
is the actual value
For student 1:
Percent error:
For student 2:
Percent error:
For student 3:
Percent error:
For student 4:
Percent error:
So, student 4 has the largest percent error.

Since we can't divide by zero, we need to find when:
But before, we can factor the numerator and the denominator:
Now, we can conclude that the vertical asymptotes are located at:
so, for x = -3:
For x = 4:
