Answer:
3×(3×7)
Step-by-step explanation:
Just move the perenthasies to the right
The min or max of a parabola/quadratic function is the vertex
for
y=a(x-h)²+k
the vertex is (h,k)
so
vertex/min is at (-1,2)
h=-1
k=2
y=a(x-(-1))²+2
y=a(x+1)²+2
find a
given, (2,20) is on the graph
20=a(2+1)²+2
20=a(3)²+2
20=9a+2
minus 2 both sides
18=9a
divide by 9
2=a
y=2(x+1)²+2 is da equation
3rd one
f(x)=2(x+1)²+2
Total juice boxes = 3 + 1 + 2 + 4 = 10
probability first one out is grape = 2 / 10
probablility second one out is grape 1 / 9 (one taken already and only nine left)
total probability = 2 / 10 x 1 / 9 = 2 / 90 = 1 / 45
