12. How could you write a system of inequalities using the quadratic functions in

the graph so that (6, 6) is a solution to the system but (6, -6) is not a solution to
the system.

Final answer:

To write a system of inequalities using the quadratic functions in the graph, use y ≤ f(x) for (6, 6) and y > f(x) for (6, -6).

Step-by-step explanation:

To write a system of inequalities using the quadratic functions in the graph, we need to determine the inequality symbols that represent the relationship between the given points and the quadratic function. Since (6, 6) is a solution to the system, it means that the point lies on or below the graph. Therefore, the inequality is represented as y ≤ f(x), where f(x) is the quadratic function graphed. On the other hand, since (6, -6) is not a solution to the system, it means that the point lies above the graph. Therefore, the inequality is represented as y > f(x), where f(x) is the quadratic function graphed.

Answer:

To write a system of inequalities that has the point (6, 6) as a solution but not (6, -6), we can use the fact that the point (6, 6) is above the graph of the quadratic function, but the point (6, -6) is below the graph. Therefore, we can write a system of inequalities that includes the condition that the y-value must be greater than the value of the quadratic function at a given x-value.

For example, we could use the quadratic function y = x^2 and write the following system of inequalities:

y > x^2

y > 6

The first inequality states that the y-value must be greater than the value of the quadratic function at a given x-value. The second inequality is added to ensure that the y-value is greater than 6, which is necessary for the point (6, 6) to be a solution.

Since the point (6, 6) satisfies both of these inequalities, it is a solution to the system. However, the point (6, -6) does not satisfy the first inequality, since the y-value is less than the value of the quadratic function at x = 6. Therefore, it is not a solution to the system.

Overall, the system of inequalities would be as follows:

y > x^2

y > 6
