NFL Rookie Wage Scale Salaries, in millions of dollars, for rookies selected in the first round of the NFL 2014 draft can be approximated by the quadratic model $$y=0.0258 x^{2}-1.30 x+23.3 $$ where $x$ represents draft pick order. Players selected earlier in the round have higher salaries than those selected later in the round. (Source: www.forbes.com) (a) Use the model to estimate the salary of the player selected first overall to the nearest tenth of a million dollars. (b) What is the estimated salary of the player selected 10 th overall? Round to the nearest tenth of a million dollars.

Key Concepts

Quadratic Functions

Quadratic functions are second-degree polynomials in the form y = ax² + bx + c. They are significant in various fields because they describe parabolic relationships, allowing for the modeling of phenomena that have a peak or minimum value and change in a non-linear fashion.

Function Evaluation

Function evaluation involves substituting a specific input value into a function to determine the corresponding output. This technique is essential for using mathematical models to predict outcomes based on given parameters.

Real-World Modeling

Real-world modeling utilizes mathematical functions, such as quadratic equations, to describe and predict real-life situations. It helps translate abstract mathematical formulas into practical estimates of values in various applications.

Rounding

Rounding is the process of reducing the number of decimal places in a number to simplify the result, making it easier to interpret. It ensures that numerical answers are presented in a clear, practical format without unnecessary precision.
