Answer:
a v-shaped graph with a minimum at (-2,-1) and x-intercepts at -1 and -3
Step-by-step explanation:
if you need to graph the function then start by creating an x-y table of values:
when x=0, y=1
so you the point: (0, 1)
when x=2, y=3
you have another point: (2,3)
when x=-2, y = -1
third point: (-2,-1)
when x=-3, y = 0
fourth point: (-3,0)
Answer:
The answer is "undefined, 1, undefined, undefined, and -1".

Answer:
equation A describes the line
Step-by-step explanation:
(x,y) = (9,1)
1 -1 = (9-9) 5/3
or, 0 =0
<span>∇ · (|r| r)

</span>
|r| =√x²+y²+z²
<span>∇ · ( r) =dr/dx +dr/dy+dr/dz= i+j+k
so
