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
