Question

Y=x2+1 принадлежит ли точка а(23;57)

Answer 1

Точка А не принадлежит этому графику у=х*2+1.
23*2+1=47
47не равно 57

Answer 2

To check whether the point A(23, 57) lies on the curve defined by the equation y = x^2 + 1, you need to substitute the x-coordinate (23) into the equation and see if the resulting y-coordinate matches the given y-coordinate (57).

Let's do the calculation:

y = x^2 + 1 y = 23^2 + 1 y = 529 + 1 y = 530

The calculated y-coordinate for x = 23 is 530, which does not match the given y-coordinate of 57. Therefore, the point A(23, 57) does not lie on the curve defined by the equation y = x^2 + 1.
