Answer 2

Checking the Points on the Function

To determine if the points A(1, -4) and B(2, 5) belong to the function u=3x-1, we can substitute the x-coordinates of the points into the function and check if the resulting y-coordinates match the given points.

For point A(1, -4): - Substituting x=1 into the function u=3x-1 gives: - u = 3*1 - 1 - u = 3 - 1 - u = 2

For point B(2, 5): - Substituting x=2 into the function u=3x-1 gives: - u = 3*2 - 1 - u = 6 - 1 - u = 5

Conclusion

The calculated y-coordinates for the given x-coordinates of points A and B match the given y-coordinates. Therefore, both points A(1, -4) and B(2, 5) belong to the function u=3x-1.
