# Absolute maximum and minimum

Find the absolute maximum and absolute minimum values of f on the given interval.

F(x) = sqrt(9-x^2) [-1, 2]

or in other words:

F(x) equals the square root of (9 minus x squared).

The problem is also attached in MS word.

#### Solution Preview

F(x) = sqrt(9-x^2) = (9-x^2)^(1/2)

on the interval [-1,2];

are standard notations for writing this equation out in text form. The ^ means exponent.

Steps:

To find the absolute max and min we have to:

1) find all extreme (or critical points)

2) check the end points.

Calculate the first derivative.

F'(x) = 1/2 (9 - x^2)^(-1/2) (-2x) = - x / sqrt(9-x^2)

(remember to use the chain ...
