Experts fear that without conservation efforts. tiger could disappear from the wild by 2022. Just out hundred years ago there were at least 100,000 wild tigers, By 2010, the estimated world tiger population was 3200. The bar graph shows the estimated world tiger population for selected years from 1970 through 2010. Also shown is a polynomial function, with its graph, that models the data. Use this information to solve Exercises 73-

a. Find and interpret f(10). Identify this information as a point on the graph of f.
b. Does f(10) overestimate or underestimate the actual data shown by the bar graph? By how much?
c. Use the Leading Coefficient Test to determine the end behavior to the right for the graph of f, Might this function be useful in modeling the world tiger population if conservation efforts to save wild tigers are successful? Explain your answer.

- Pls help ASAParrow_forwardThe polynomial function f(x) = -0.27x3 + 9.2x2 - 102.9x + 400 models the ratio of students to computers in U.S. public schools x years after 1980. Use end behavior to determine whether this function could be an appropriate model for computers in the classroom well into the twenty-first century. Explain your answer.arrow_forwardidentify some real-life applications of polynomial functions. Name a few and explain in at least three sentences why it is an application of a polynomial function.arrow_forward
- The bar graph shows the differences among age groups on the Implicit Association Test that measures levels of racial prejudice. Higher scores indicate stronger bias. Solve, a. The data can be described by the following polynomial model of degree 3: S = 0.2x3 - 1.5x2 + 3.4x + 25 + (0.1x3 - 1.3x2 + 3.3x + 5). In this polynomial model, S represents the score on the Implicit Association Test for age group x. Simplify the model. b. Use the simplified form of the model from part (a) to find the score on the Implicit Association Test for the group in the 45–54 age range. How well does the model describe the score displayed by the bar graph?arrow_forwardThe graph below represents the profit of a company, in thousands of dollars, over a 6 month period beginning in October 2018. Use the graph to answer the questions a)Explain why an exponential or logarithmic function would not be used to model this graph. b)What is the minimum possible degree polynomial that can model this graph? c)Find the x-intercept(s) and interpret their meaning in this context. d)When (give name of month and year) was the profit at its lowest level, and what does this value mean? e)When (give name of month and year) did the profit reach its maximum?What was the company’s profit at that time?arrow_forwardHow do we call a function that is not a polynomial?arrow_forward
- Write equations for several polynomial functions of odd degree and graph each function. Is it possible for the graph to have no real zeros? Explain. Try doing the same thing for polynomial functions of even degree. Now is it possible to have no real zeros?arrow_forwardWhat do you think the factored form of any polynomial would tell you about the behavior of the related functions graph?arrow_forwardThe graph of a polynomial function is given. What is the smallest degree that the polynomial could have? The smallest degree the polynomial could have is. (Simplify your answer.) Enter your answer in the answer box.
