Complete the table of values fory=2x^2+x

Complete question:

y = 2x² + 2x - 3

x = - 2 - 1 0 1 2

Answer:

Complete table of values

x: - 2 - 1 0 1 2

y: 1 - 3 - 3 1 9

Step-by-step explanation:

Given;

y = 2x² + 2x - 3

To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.

when, x = - 2

y = 2 (-2) ² + 2 (-2) - 3

y = 8 - 4 - 3

y = 1

when x = - 1

y = 2 (-1) ² + 2 (-1) - 3

y = 2 - 2 - 3

y = - 3

when x = 0

y = 2 (0) ² + 2 (0) - 3

y = 0 - 0 - 3

y = - 3

when x = 1

y = 2 (1) ² + 2 (1) - 3

y = 2 + 2 - 3

y = 1

when x = 2

y = 2 (2) ² + 2 (2) - 3

y = 8 + 4 - 3

y = 9

Complete table

x: - 2 - 1 0 1 2

y: 1 - 3 - 3 1 9
