Please help me with this question urgently! Thanks in advance.

Step-by-step explanation:

First. plug in values of x and try to form a curve. Since this a quadratic, we will get a parabola( a U shaped graph).

Plug in values from -3 to 4.

for x.

Keep going until you get until you get to 4 for x.

The graph above should be your curve.

1. The roots of a quadratic are the x values when y=0, here it is 2.5 and -1.

2. Since the leading degree coeffecient is positive, we have a minimum value. It hard to tell the minimum here so let put this in vertex form, we have

First. we do

Now, we plug that in to find our y intercept of the minimum.

So we have

(3/4,-98/16).

or

(3/4,-6.125).

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
