Being a positive real number and not-null, consider the functions:
f: R --> R; f(x) = ax² + 2 e g : [2;1) --->R+; g(x) = sqrt[(x-2)/a]
Their graphics on a cartesian plan intercept only at two distinct points M and N.
(a)Determine the minor real interval in which the number (a) is necessarily contained.
(b)Knowing this way between M and N 3.sqrt(2) determine the value of (a).
