The statements are true about the graphs of all nth degree polynomials are B and D.
B. It goes up and down at most a total of n times.
D. The number of x-intercepts is at most n.
Y=15x would be the correct graph though if there's more info it might not be
For the 2017-2018 school year, the average costs for one year of education is:
Tuition/Fees: $4,391
Living Costs: $10,406
Books/Supplies: $1,724
Transportation: $2,313
Other Expenses: $3,025
With the given 7% inflation rate, the average cost will increase for the next session (2018-2019).
Hence, for year 2017-2018 the total expense will be sum of all the given costs.
= $4,391 + $10,406 + $1,724 + $2,313 + $3,025
= $21,859
