Question:

Solution:

A quadratic Equation in Standard Form is given by the following formula:

[tex]ax^2+bx\text{ + c = 0}[/tex]

now, the given equation is

[tex]y=-x^2+9[/tex]

this is equivalent to:

[tex]f(x)=-x^2+9[/tex]

According to the Quadratic Equation in Standard Form, we can conclude that

[tex]a\text{ = -1}[/tex][tex]b\text{ = 0}[/tex]

and

[tex]c\text{ = 9}[/tex]
