Answer:
f(x)= -2(x-8)²+6
Step-by-step explanation:
First graph the points
you will get a parabola that has a vertex in (8,6) wich means h= 8 and k=6
so the equation is
to get a we will replace by the coordinates of a point for example (6,-2)
- -2 = a(6-8)²+6
- -2 = a*4+6
- -2-6 = 4a
- -8 = 4a
- a = -2
a is negative wich makes sense since the parabola opens down
X/7 = 0.4 => x = 7 x 0.4 = 2.8
7/y = 0.4 => y = 7 : 0.4 = 17.5
The number would be 84 because 48 rounds up to 50 while 84 rounds down to 80.
