tentukan nilai stasioner dari fungsi f(x)=x²-5x+6 tolong jawab yang jelas dan betul ya

f(x) = x² - 5x + 6
f'(x) = 2x - 5
syarat nilai stasioner: f'(x) = 0

0 = 2x - 5
x = 5/2

Nilai Stasioner
f(5/2) = (5/2)² - 5 (5/2) + 6
f(5/2) = 25/4 - 25/2 + 6

f(5/2) = 81 (nilai stasioner)

f(x) = x^2 - 5x + 6
f'(x) = 2x - 5 = 0 => 2x = 5 => x = 5/2
Nilai stasioner nya :
f(5/2) = (5/2)^2 - 5(5/2) + 6
= 25/4 - 25/2 + 6
= 25/4 - 50/4 + 24/4
= -1/4 => nilai stasioner (nilai balik minimum)
