Answer:
Step-by-step explanation:
y =2x^2-5x + 12
a = 2, b = -5
Vertex of X-coordinate = -b/2a
= -(-5)/2(2)
= 5/4
Vertex of Y-coordinate = f(5/4)
= 2(5/4)^2 - 5(5/4) + 12
= 2(25/16) - 25/4 + 12
= 25/8 - 25/4 + 12
= (25- 50 + 96)/8
= 71/8
yd=
16x2+12x+18=3x=2x2+6x+9=3x=
sorry i try
The answer would be 1.25.
