Question

6. What is the relative maximum and minimum of the function?

f(x)= x^3 + 6x^2 – 36x

The relative maximum is at (–6, 216) and the relative minimum is at (2, –40).
The relative maximum is at (–6, 40) and the relative minimum is at (2, –216).
The relative maximum is at (6, 216) and the relative minimum is at (–2, –40).
The relative maximum is at (6, 40) and the relative minimum is at (–2, –216).

8. Over two summers, Ray saved $800.00 and $600.00. The polynomial represents his savings at the beginning of the third year, where x is the growth factor. (The interest rate r is x – 1.) What is the interest rate he needs to save $1,650.00 after the third summer?

800x2 + 600x (1 point)
