y is the quadratic function of x. Given below is an incomplete table containing the values ​​of y corresponding to several values ​​of x.

X

-4

-3

-2

-1

0

1

0

y

5

-3

-4

-3

I. Find the value of y when x = -3 by considering the symmetry of the quadratic function.

II. Draw the graph of the function using an appropriate scale.

** According to your chart,

Write the range of values ​​of x over which the function is negative.

Express the above quadratic function as y = (x+a) (x - b). (a and b are integers.)

- If the above function is changed to form y = (a + x) (b - x), write the coordinates of its turning point.
