a. Answer Attendance went down at first and then slowly it started increasing again. Explanation From the given graph it can be observed that the during the first four weeks after flu outbreak, attendance went down from 450 to 350 and after that from 5 t h week onwards it again started increasing and by 16 t h week it again reached 450 level. b. To determine To estimate: A ( 13 ) and explain its meaning. Answer Approximately 425 Explanation By looking at the given graph, it can be observed that when x = 13 , A ≈ 425 . This implies that, the number of students that attended high school 13 weeks after the flu outbreak is approximately 425. c. To determine To estimate: solutions of the equation A ( x ) = 400 . Answer Attendance went down at first and then slowly it started increasing again. Explanation Observe the given graph, By looking at the above graph it can be said that the values of x corresponding to A = 400 are x = 1 and x = 10 . This means that the number of students that attended the high school is 400 during the 1 s t week and the 10 t h week. d. To determine To find: the least attendance and the week during which that happens. Answer Least attendance = 350 Week = 4 t h Explanation Observe the given graph, By looking at the above graph it can be said that the least attendance is 350 and it happens during the 4 t h week. e. To determine To find: the number of students enrolled in high school. Answer 450 Explanation Assume that there was perfect attendance during the week before the flu outbreak. Then, the value of A corresponding to x = 0 gives the total number of students in high school. Observing the given graph, it can be said that the number of students in high school enrolled is 450

This implies that, the number of students that attended high school 13 weeks after the flu outbreak is approximately 425.

To determine

To estimate: solutions of the equation A(x)=400 .

Expert Solution

Answer to Problem 34E

Attendance went down at first and then slowly it started increasing again.

Explanation of Solution

Observe the given graph,

BIG IDEAS MATH Algebra 1: Common Core Student Edition 2015, Chapter 3.3, Problem 34E , additional homework tip 2

By looking at the above graph it can be said that the values of x corresponding to A=400 are x=1 and x=10 .

This means that the number of students that attended the high school is 400 during the 1^s^t week and the 10^t^h week.

To determine

To find: the least attendance and the week during which that happens.

Expert Solution

Answer to Problem 34E

Least attendance = 350

Week = 4^t^h

Explanation of Solution

Observe the given graph,

BIG IDEAS MATH Algebra 1: Common Core Student Edition 2015, Chapter 3.3, Problem 34E , additional homework tip 3

By looking at the above graph it can be said that the least attendance is 350 and it happens during the 4^t^h week.

To determine

To find: the number of students enrolled in high school.

Expert Solution

Answer to Problem 34E

450

Explanation of Solution

Assume that there was perfect attendance during the week before the flu outbreak.

Then, the value of A corresponding to x=0 gives the total number of students in high school.

Observing the given graph, it can be said that the number of students in high school enrolled is 450
