Short Answer

Expert verified

The required graph is:

Step by step solution

01

Step 1. Given information.

The given equation isy=-x2+8x-16.

02

Step 2. Determine the parabola is open up or down by using the properties.

Compare the given parabola y=-x2+8x-16with y=ax2+bx+c.

So, here a=-1,b=8,c=-16.

If a=-1<0, then the parabola open down.

03

Step 3. Draw the graph.
