Answer with explanation:</h2>
The given function : 
Using completing the squares, we have
[∵ 
]
(1)
Comparing (1) to the standard vertex form 
, the vertex of function is at (h,k)=(-1,-4)
For x-intercept, put f(x)=0 in (1), we get
Square root on both sides, we get
∴ x intercepts : x= (-3,0) and (1,0)
For y-intercept put x=0 in (1), we get
∴ y intercept : (0,-3)
Axis of symmetry : 
In , a=1 and b=2
Axis of symmetry=
Answer:
if a function has degree 9
it will have 9 roots
given 3 are real this means rest (9-3 =6) are not real which means complex
2+2
<span> ↑
</span>That is an expression. Make sure you don't put the "=" sign since it would become an EQUATION if you did.
360=2w+2l
l=8+w
Substitute for l
360=2w+2(8+w)
360=2w+16+2w
360=4w+16
344=4w
86=w
Plug in the w value
l=8+(86)
l=94
Final answer: Length-94 inches, Width-86 inches
