Provide a rule for an example of a nonlinear function that fits the following description: When \( d = 4 \), \( r = 9 \), and \( r \) is a function of \( d \).
Answer (2)
A rule for a **nonlinear **function that fits the given description is r is a function of d. One example of such a function is r = d^2 - 5d + 6. When d is 4, the corresponding r value is 2. ;
The nonlinear function r = d^2 - 7 fits the given description, as it outputs r = 9 when d = 4. This illustrates a quadratic relationship between r and d. Quadratic functions are a common example of nonlinear functions.
