(HELP PLEASE) Select all of the statements that can be determined from the table given.



A. There is a y-intercept at (-4,0).

B. There are x-intercepts at (-1,0) and (4,0).

C. There is a line of symmetry at x=1.5

D. In the interval from x=0 to x=5, F(x) is increasing.

HELP PLEASE Select all of the statements that can be determined from the table given A There is a yintercept at 40 B There are xintercepts at 10 and 40 C There class=

Respuesta :

B, C are your answers. The other two are false. Vertex is at x = 1.5 y = -7

Answer:

B. There are x-intercepts at [tex](-1,0)[/tex] and [tex](4,0)[/tex]


C. There is a line of symmetry at [tex]x=1.5[/tex]

Step-by-step explanation:

we know that

The x-intercepts are the values of x when the value of the function is equal to zero

The y-intercepts are the values of y when the value of x is equal to zero

Observing the table

The  x-intercepts are the points [tex](-1,0)[/tex] and [tex](4,0)[/tex]

The  y-intercept is the point [tex](0,-4)[/tex]

Plot the points

The axis of symmetry is [tex]x=1.5[/tex] ----> the x-coordinate of the vertex is [tex]1.5[/tex]

The function is increasing in the interval-----> (1.5,∞)

The function is decreasing in the interval-----> (-∞, 1.5)

therefore

Statements

B. There are x-intercepts at [tex](-1,0)[/tex] and [tex](4,0)[/tex]

The statement is True


C. There is a line of symmetry at [tex]x=1.5[/tex]

The statement is True --------> see the attached figure
