Question

Graph the equation y= -x² + 10x - 16. you must plot 5 points including the roots and the vertex

Answer 1

Given the function:

`y=-x^2+10x-16`

The graph of the function is plotted and attached below:

From the graph:

• The roots are (2,0) and (8,0).

,

• The vertex is a maximum that occurs at (5,9)

,

• The graph intersects the y-axis at (0,-16).

The other points are added as a guide when plotting your own graph.
