Respuesta :

Note that the intercept with the x-axis is not (0,1) and (0,-3), it is closely to them, but not equal.

The line of symmetry is x = -1 (true).

The maximum is (-1,6) (True): note that the maximum value (positive value) has coordinate (-1,6).


ANSWER

Options B and C are the correct answers



EXPLANATION

The x intercepts are the point at which the graph crosses the x-axis.


The value of y for the x intercepts are zero but for the given options, the y values are not zero, therefore (0,-1) and (0,-3) are not x-intercepts.


The option A is not true.


The vertex of the parabola is

[tex](-1,6).[/tex]


This is the maximum point on the parabola.


The vertical line through the vertex of the parabola is the axis of symmetry of the parabola which is
[tex]x = - 1[/tex]



Therefore the correct answers are option B and C.
