Generating ordered pairs is to solve for "y" using the function above with the given "x" values -4, -2, 0, 2, and 4.
If x = -4, then y = 7.
y = (-4)² - 9
y = 16 - 9
y = 7
If x = -2, then y = -5.
y = (-2)² - 9
y = 4 - 9
y = -5
If x = 0, then y = -9
y = 0² - 9
y = 0 - 9
y = -9
If x = 2, then y = -5
y = 2² - 9
y = 4 - 9
y = -5
If x = 4, then y = 7
y = (4)² - 9
y = 16 - 9
y = 7
To summarize, the ordered pairs for the function y = x² - 9 using the given x - values are:
1. (-4, 7)
2. (-2, -5)
3. (0, -9)
4. (2, -5)
5. (4, 7)
Below is the graph of the equation. Due to the nature of the equation, the graph is a parabola.
