Answer:
Step-by-step explanation:
It is hard to guess the coordinates of any points, because the graph doesn't go through any intersections of the grid.
Fortunately, I can tell that the axis of symmetry is x=2.
Put the equation into vertex form by completing the square.
axis of symmetry = b/2
b/2 = 2
b = 4

The statement that correctly compares the students’ test scores is that the median of Jen's score is greater than the median of Ron's score.
<h3>How to find mean and median?</h3>
Jen and Ron each took five tests. There test score are as follow:
- Jen: {45, 91, 84, 66, 74}
- Ron: {70, 95, 99, 69, 72}
Let's find the mean and median of the test score to compare them correctly
Jen: {45, 66, 74, 84, 91}
mean of Jen score = 45 + 66 + 74 + 84 + 91 / 5
mean of Jen score= 360 / 5
mean of Jen score = 72
Median of Jen score = 74
Ron: {69, 70, 72, 95, 99}
mean of Ron score = 69 + 70 + 72 + 95 + 99 / 5
mean of Ron score = 405 / 5
mean of Ron score = 81
median of Ron score = 72
Therefore, the median of Jen's score is greater than the median of Ron's score.
