Question

let f(x) = x^4-2x^2+3, [-2,3]. a. find critical numbers of f b. find the absolute maximum and absolute minimum values of f

Answer 1

Find f'
Then set f'=0
See if there are any values of x that satisfy f'=0 that are also between -2 and 3
Then you will do
f(-2)
f(3)
f(any values that satisfy f'=0 )

Answer 2

f( any values that satisfy f'=0 and is btw -2 and 3 )*
