Question

Find the absolute minimum and absolute maximum values off on the given interval.

f(x)=x²³ - 6x² + 9x+2, [-1,9]

Answer 1

min = -14; max = 326

Explanation:

Assuming this is actually supposed to be f(x)=x³ - 6x² + 9x+2, instead of f(x)=x²³ - 6x² + 9x+2:

Find f(-1) = (-1)³-6(-1)²+9(-1)+2 = -14

and f(9) = (9)³-6(9)²+9(9)+2 = 326
