Answer:
So a point is (-3,-5) and the vertex is (-4,-3)
Step-by-step explanation:
This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.
The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)
I will choice -3. This gives -2(-3+4)^2-3
f(-3)=-2(1)^2-3
f(-3)=-2-3
f(-3)=-5
So a point is (-3,-5) and the vertex is (-4,-3)

Answer:
do the rest urself
Step-by-step explanation:
-7 1/5= -36/5
-4 2/3= -14/3
-14/3-(-3
6+3x=x-8 subtract 6 from both sides
3x=x-14 subtract x from both sides
2x=-14 divide both sides by 2
x=-7
This equation thus has just one solution.
