plz dont copy paste from Google
tomorrow I'm having exam
so plz dont cheat​

Answer 1

differentiate the function and equate it to zero

you will get a value of x

substitute it in the function

you will get either max or min value of the function

to find whether the value we get is max or min

just differentiate the function twice and the value of the function

if less than zero you get max value

if greater than zero you get min value
