Answer 1

the minimum when X=5 and point of inflection is X=2

Answer 2

how can the minimum be 5?

Answer 3

if this is to have a minimum, it is pretty clear that \(a>0\) or else there is no minimum
if \(a>0\) then \(f(0)=0\)

Answer 4

still not getting it

Answer 5

@satellite73 i dont understand how to solve it
