tutorsd6 : Please, share your Math problem...
student : we need to determine whether f(x)=4x-x(squared)+1
student : is a maximum or a minimum
student : then find the value
tutorsd6 : f( x ) = 4x - x^2 + 1
tutorsd6 : dy/dx = 4 - 2x
tutorsd6 : d2y / dx^2 = 4 > 0 ,,,,so it is minimum
student : now what is the value
