Answer:

Step-by-step explanation:
we know that

Is the equation of a vertical parabola written in vertex form
where
(h,k) is the vertex
a is the leading coefficient
In this problem we have
The vertex is the point (-1,4)
so

substitute

Find the value of a
we have the ordered pair (0,3)
substitute the value of x and the value of y in the quadratic equation and solve for a


therefore

Answer:
The unit rate is $0.37 per popsicle.
Step-by-step explanation:
Unit rate represents the rate per one unit. In this case, the unit rate would represent the cost per popsicle. Since one box contains a total of 12 popsicles, we need to take the total cost of the box ($4.44) and divide by the number of popsicles that come in the box, or 4.44/12. When we divide, we get 0.37, or $0.37 per popsicle.
