The points (-3, 9), (-1, 1), (0, 0), (1, 1) and (3, 9) lie on the graph of the function y = x²
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation y = x²
When x = -3; y = (-3)² = 9
When x = -1; y = (-1)² = 1
When x = 0; y = (0)² = 0
When x = 1; y = (1)² = 1
When x = 3; y = (3)² = 9
The points (-3, 9), (-1, 1), (0, 0), (1, 1) and (3, 9) lie on the graph of the function y = x²
