Question

find maxima and minima of f(x)=2x³-9x²+12x+3 plzz guys
solve this​

Answer 1

Answer:

x=2 is point of Minima and x=1 is point of Maxima.

Step-by-step explanation:

f'(x) = 6x^2 - 18x +12

f'(x) = 0

6x^2 - 18x + 12 = 0

x^2 - 3x + 2 = 0

x^2 - 2x - x +2 = 0

(x-2)(x-1) =0

f''(x) = 12x-18

For x=2, f''(x)>0

So x=2 is point of Minima of f(x).

For x=1, f''(x)<0

So, x=1 is point of Maxima of f(x).
