Q4) Find the local and absolute extreme values of the function on the given
interval.
1. f(x) = x* – 6x² + 9x + 1, [2, 4]
2. f(x) = x/T – x , [-1, 1]
3x - 4
3. f(x) =
[-2, 2]
x² + 1'
4. (x) = /x² + x+ I, [-2, 1]
Q5) Find the limit. Use l'Hospital's Rule where appropriate. If there is a more
elementary method, consider using it. If l'Hospital's Rule doesn't apply, explain
why.
