The data suggests that there are two turning points, therefore, a cubic function is a better representation than a quadratic function. Using the cubic regression function on a graphing calculator, we get \(f(x)=5.754x^3+2.912x^2-7.516x+0.349\)

If John, Trey, and Miles want to know how’ |
many two-letter secret codes there are that don't
have a repeated letter. For example, they want to
: count BA and AB, but they don't want to count“ doubles such as ZZ or XX. Jobn says there are
26 + 25 because you don’t want to use the same
letter twice; that’s why the second number is 25.

‘Trey says he thinks it should be times, not plus: 26-25, Miles says the number is 26-26 ~ 26 because you need to take away the double letters. Discuss the boys’ ideas, Which answers are correct, which are not, and why? Explain your answers clearly and thoroughly, drawing ‘on this section’s definition of multiptication.. -
