We know that
The Standard Form<span> of a </span>Quadratic Equation<span> is
</span> ax²<span> + bx + c = 0
</span>
then
for x=0 y=-6
a*0² + b*0 + c = -6---------> c=-6
for x=1 y=2
a*1² + b*1 -6 = 2---------> a+b=8---------> a=8-b---------> equation 1
for x=3 y=-0
a*3² + b*3 -6 = 0---------> 9a+3b=6---------> equation 2
<span>substituting 1 in 2
9*(8-b)+3b=6------> 72-9b+3b=6---------> 6b=66--------> b=11
a=8-11-------> a=-3
so
a=-3
b=11
c=-6
</span>Standard Form of a Quadratic Equation is
-3x² + 11x - 6 = 0
<span>
the answer is
</span> -3x² + 11x - 6 = 0<span>

Answer:
(x, y) ⇒ (x -2, y +2)
Step-by-step explanation:
Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).
Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).
The composition of these transformations is then ...
(x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)
Answer:
1 cup = 8 fl oz
Step-by-step explanation:
1 cup = 8 fl oz
You just plug in the -2 for x to get the equation -2^2–3•-2+4= 6
