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)
