N= -4
-4/2+5=3
-2+5=3 you have to subtract the 5 from three first and then multiply the answer by 2 to get n
As it stands, it's none of those. I believe you were going for the distance formula but copied it wrong.
Dy/dx=2x+2
So velocity will be zero when 2x+2=0, x=-1
Since d2y/dx2=2, it has a constant positive acceleration of 2, so that when dy/dx=0 it is at an absolute minimum value for f(x), which is also the vertex.
y(-1)=1-2+3=2
So the vertex is at (-1,2), which is an absolute minimum so the parabola opens upwards.
And by symmetry we can say that f(0)=f(-2)=3 so you have another two points that you can see (-2,3) and (0,3)
Answer:
Can you be a litte more specific
Step-by-step explanation:
Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is 
.
Now question says to find the y-intercept of the given parabola .
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation then solve that for y.
Hence the y-intercept is (0,-12).
