Consider the function f(x, y, z) = x 2−3y 2−z 2 . All parts refer to this function f. a. Find the absolute maximum and absolute minimum values of f(x, y, z) subject to the constraint x 2 + y 2 + z 2 = 9.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the answer to this in exact form is 4/35 but in decimal form its 0.1142857
