f(x) = x³ - 6x² + 9x + 15 എന്ന ഏകദത്തിന്ടെ പ്രാദേശിക ഉന്നത വില ബിന്ദു ഏത്?

Ax=3

Bx=1

Cx=-3

Dx=4

Answer:

B. x=1

Read Explanation:

f'(x) = 3x²-12x+9 f'(x)= 0 => 3(x² - 4x + 3) = 0 x=1 ; x=3 f''(x)=6x - 12 f''(1) = 6 - 12 = -6 < 0 ; x=1 maxima f"(3) = 6 x 3 -12 = 6 > 0 ; x=3 minima x=1 => ഉന്നത വില
