Grafik fungsi kuadrat y= x²-5x+m melalui titik (-3,17). titik berikut yg tidak dilalui fungsi kuadrat y ….

(-3,17) –> x = -3, y = 17
17 = (-3)² -5(-3) + m
17 = 9 + 15 + m
m+24 = 17
m = -7

jadi y = x² -5x – 7
a. (1,-11)
-11 = 1² -5(1) -7
-11 = -11 ✓

b. (-1,-1)
-1 = (-1)² -5(-1) -7
-1 = 1 + 5 -7
-1 = -1 ✓

c. (3,-17)
-17 = (3)² -5(3) -7
-17 = -13 ×

d. (2,-13)
-13 = 2² -5(2) – 7
-13 = -6 – 7
-13 = -13 ✓

yg gak dilalui yg c titik (3,-16)
