I need some help please with two revision questions.
I read my Calculus book and I did not understand it!
Suppose that 3<= f ' (x) <= 5 for all values of x. Determine the highest and lowest possible values for the expression A = f (8) - f (2).
Am I meant to use "MVT" ??
For what values of the numbers a and b does the function f(x) = axe^bx²
have the maximum value f(2) = 1? Give reasons.
Sorry this I do not know.
