Answer 1

The complete table of values is

x y

-1 2

0 -2

1 -4

2 2

3 -2

How to complete the table of values

To complete the table of values for the quadratic function y = x² - 3x - 2, we can substitute the given values of x into the expression and calculate the corresponding y values.

For x = -1

y = (-1)² - 3(-1) - 2 = 2

So, A = 2

For x = 0

y = (0)² - 3(0) - 2 = -2

B = -2

For x = 3

y = (3)² - 3(3) - 2 = -2

So C = -2
