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:
h = 5.5
Step-by-step explanation:
2.3 + h = 7.8
-2.3 -2.3
h = 5. 5
Answer:
B, because thats dividing, which equals 3. for the answer A, did you mean 15*5?
Step-by-step explanation:
21 fewer stars than three times a number h
21 - (3 x h)
