Question

3. 4. Чи належать графіку функції y = x ^ 2 - 3 точки E(- 4; - 19) B(5;22)?​

Answer 1

1) проверим т .Е ( -4; -19)
У=х^2 -3
(-4)^2 -3 = 16-3=13
У=13
Т. Е (-4;-19) - не принадлежит графику=х^2-3

2) т.В (5:22)
У= 5^2-3
У= 22
Т. В(5,22) - принадлежит графику у=х^2-3

Answer 2

Function and Points

The function is given as y = x^2 - 3 and the points are E(-4, 19) and B(5, 22).

Calculating the Values

To check if the points belong to the function, we can substitute the x-coordinates of the points into the function and see if the resulting y-coordinates match the given points.

For point E(-4, 19): Substituting x = -4 into the function y = x^2 - 3 gives: y = (-4)^2 - 3 = 16 - 3 = 13

For point B(5, 22): Substituting x = 5 into the function y = x^2 - 3 gives: y = (5)^2 - 3 = 25 - 3 = 22

Conclusion

The calculated y-coordinates for the given x-coordinates of the points match the given points. Therefore, both points E(-4, 19) and B(5, 22) belong to the function y = x^2 - 3.
