Question

Copy and complete the table of values for

y = 2x² + x + 4.
What numbers replace A and B?
x
y
-2 -1 0 1 2
A 5 4 B 14

Answer 1

The numbers that replace A and B in the table are 10 and 5 respectively.

Step-by-step explanation:

To complete the table of values for the equation y = 2x² + x + 4, you need to substitute the given values of x into the equation and solve for y.

For x = -2, substitute -2 into the equation:

y = 2(-2)² + (-2) + 4

= 2(4) - 2 + 4

= 8 - 2 + 4

= 10.

For x = -1, substitute -1 into the equation:

y = 2(-1)² + (-1) + 4

= 2(1) - 1 + 4

= 2 - 1 + 4

= 5.

So, the values that replace A and B in the table are A = 10 and B = 5.
