Question

какая из точек А, В принадлежит графику функции у=f(x),если f(x)=x в -6, А(корень из 2;1\8), В(1\2; 64)

Answer 1

ответ в

1/2 в степени -6 =2 в степени 6=64

Answer 2

Function and Points

The function is given as f(x) = x. We need to determine whether the points A(√2, 1/8) and B(1/2, 64) belong to the graph of this function.

Point A

The x-coordinate of point A is √2 and the y-coordinate is 1/8.

Point B

The x-coordinate of point B is 1/2 and the y-coordinate is 64.

Verification

To check if a point belongs to the graph of a function, we need to verify if the y-coordinate of the point is equal to the function value at the given x-coordinate.

For point A: - x-coordinate: √2 - y-coordinate: 1/8 - Function value at x = √2: f(√2) = √2

For point B: - x-coordinate: 1/2 - y-coordinate: 64 - Function value at x = 1/2: f(1/2) = 1/2

Conclusion

- Point A(√2, 1/8) does not belong to the graph of the function f(x) = x. - Point B(1/2, 64) belongs to the graph of the function f(x) = x.

Therefore, point B(1/2, 64) belongs to the graph of the function f(x) = x.
