Which statements are true about the graph of the function f(x) = x2 – 8x 5? check all that apply. the function in vertex form is f(x) = (x – 4)2 – 11. the vertex of the function is (–8, 5). the axis of symmetry is x = 5. the y-intercept of the function is (0, 5). the function crosses the x-axis twice.

we have that

1) convert the function in vertex form

let

y=f(x)

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side.

Rewrite as perfect squares

the function in vertex form

so

the vertex is the point

the axis of symmetry is x=4

the y-intercept of the function is

the function crosses the x-axis twice

therefore

case a) the function in vertex form is

Is true

case b) the vertex of the function is

 is false

case c) the axis of symmetry is

is false

case d) the y-intercept of the function is

is true (see the attached figure)

case e) the function crosses the x-axis twice

is true (see the attached figure)

step-by-step explanation:

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
