Answer:
y=9*(52)(-3).
<h2>y = -1404</h2>
Step-by-step explanation:
Plug in -3 for x and then multiply.
the first one I think since the second equals to 0 and the third is 62 meaning that is is to low to be measured and the last is to high to be measured
To find the x intercepts, we need to put the standard form equation into factored form.
Which two numbers multiply to -8 and add to -2?


So the factored form is

That means the x intercepts are at 
So now we have the x intercepts.
To find the vertex, we need to convert the standard form equation into vertex form.
The formula of vertex form is 
Since the a value in the standard form equation is 1, the a value in vertex form is also one.
The h value can be found using the formula 
Which comes out to
or 1.
To find the k value, we can just plug in what we got for h back into the equation.

So the vertex is
.
This also means the axis of symmetry is 
Finally, to find the y intercept, we plug in 0 for x and solve.

So the y intercept is
.
