Question

A function contains the point (-9, 15). Which point could NOT be another point in the function?

A) (15, -9)
B) (6, 15)
C) (2, 6)
D) (-9, 14)

Answer 1

To determine which point could NOT be another point in the function, substitute the x-coordinate into the function and see if it matches the given y-coordinate. Option A) (15, -9) is the point that could NOT be another point in the function.

Step-by-step explanation:

To determine which point could NOT be another point in the function, we need to consider the x-coordinate and the y-coordinate of each point. The given function contains the point (-9, 15). The x-coordinate represents the input value, while the y-coordinate represents the output value of the function. So, if we substitute -9 into the function, the output should be equal to 15. Let's check each option.

A) (15, -9): If we substitute 15 into the function, it doesn't give us -9. So, this point could NOT be another point in the function.

B) (6, 15): If we substitute 6 into the function, it doesn't give us 15. So, this point could NOT be another point in the function.

C) (2, 6): If we substitute 2 into the function, it doesn't give us 6. So, this point could NOT be another point in the function.

D) (-9, 14): If we substitute -9 into the function, it gives us 15. So, this point could be another point in the function.

Therefore, the point that could NOT be another point in the function is option A) (15, -9).
