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 answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
