use all this information to sketch the graph of the function.

y= 1 4 (8x−x2)

Part 1) The vertex is the point (4,4)

Part 2) The x-intercepts are the points (0,0) and (8,0)

Part 3) The y-intercept is the point (0,0)

Part 4) The equation of the line of symmetry is x=4

Part 5) The graph in the attached figure

Step-by-step explanation:

The correct quadratic equation is

Part 1) Find the coordinates of the vertex

we have

This is a vertical parabola  open down (leading coefficient is negative)

The vertex is a maximum

Convert to vertex form

Factor -1

Complete the square

Rewrite as perfect squares

----> equation in vertex form

The vertex is the point (4,4)

Part 2) Find the x-intercepts

Remember that

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

so

For y=0

solve for x

Multiply both sides by 4

square root both sides

therefore

The x-intercepts are the points (0,0) and (8,0)

Part 3) Find the y-intercept

Remember that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

therefore

The y-intercept is the point (0,0)

Part 4)

Find the equation of the line of symmetry

we know that

In a vertical parabola the equation of the line of symmetry is equal to the x-coordinate of the vertex

The vertex is the point (4,4)

so

The equation of the line of symmetry is x=4

Part 5) Graph the function

we have

The vertex is the point (4,4)

The x-intercepts are the points (0,0) and (8,0)

The y-intercept is the point (0,0)
