Question

What are the table of values for y=2x^2+x+3

Answer 1

The table of values for the equation is as follows

x y

-2 9

-1 4

0 3

1 6

2 13

How to find the table of values

The table of values is solved using substitution.

Let the input values be -2 -1 0 1 2

For x = -2

y=2(-2)² + (-2) + 3 = 9

For x = -1

y=2(-1)² + (-1) + 3 = 4

For x = 0

y=2(0)² + (0) + 3 = 3

For x = 1

y=2(1)² + (1) + 3 = 6

For x = 2

y=2(2)² + (2) + 3 = 13
