Question

@Hero How do you find the maximum and minimum value of a function?

Answer 1

To find minimum and maximum value of a function you need to find its second derivative known as d^2y/dx^2

If it is >0 than its minimum value

in case it is <0 than its maximum value

Answer 2

How do you know what values you plug in to the second derivative?

Answer 3

Where do you get those from?

Answer 4

first take the first derivative and equal it to =0

thats the turning point so your parabola turns here

when you equal the derivative to zero you will get your x

now differentiate the terms again and put this x in the second derivative .

Answer 5

Got it thanks
