Question

# Please give me correct answer and explain clearly to :

Find the **maxima and/ or**

** minima** for the following function : f(x) = x3/4 – 4×2 + x

FF ) = 1/ x

14* – 4x 2 + x

Find the first derivative and equate to zero

f ( x ) = 3×2 – 8x +1 =0

solving for * you get

21 = 10.54

of ( 10 54 ) = 1/ ( 10 54)3- 4(10-54 ) + 10.54

= – 141 . 1.

* 10 ….Math
