Robb graphed the square root function shown below as part of his math assignment. Robb needs to graph the inverse function. He knows he needs to restrict the function
in order to correctly show the inverse relationship. What does Robb need to do to the
graph of the quadratic function to correctly show the relationship between the
square root function and its inverse function?

A. Restrict the domain of the quadratic function to x is greater than or equal to 5

B. Restrict the range of the quadratic function to y is greater than or equal to 5

C. Restrict the domain of the quadratic function to x is less than or equal to 5

D. Restrict the range of the quadratic function to y is less than or equal to 5

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan. (give the answer in billions rounded to the nearest hundredth) b) how does this compare to the actual value for k-12 expenditures in illinois? (lower, higher, same? )

Charlie is at an amusement park that has 18 different rides. each ride costs $1.75. the function c(r) = 1.75r represents the total amount of money that charlie will spend if he goes on r rides, but he never goes on the same one more than once. what domain and range are reasonable for the function?
