Bentuk umum fungsi kuadrat. sumbu simeteri Nilai puncak Jadii, nilai puncak

Bentuk umum fungsi kuadrat.

straight f left parenthesis straight x right parenthesis equals ax squared plus bx plus straight c

sumbu simeteri $x equals negative fraction numerator b over denominator 2 a end fraction$

Nilai puncak $f open parentheses negative fraction numerator b over denominator 2 a end fraction close parentheses$

$table attributes columnalign right center left columnspacing 0px end attributes row cell straight f left parenthesis negative fraction numerator straight b over denominator 2 straight a end fraction right parenthesis end cell equals cell straight f left parenthesis negative fraction numerator negative 6 over denominator 2 times 1 end fraction right parenthesis end cell row blank equals cell straight f left parenthesis 3 right parenthesis end cell row blank equals cell 3 squared minus 6 times 3 plus 9 end cell row blank equals cell 9 minus 18 plus 9 end cell row blank equals 0 end table$

Jadii, nilai puncak y equals 0.
