Using the quadratic formula we get
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
Answer:
The graph will be a parabola
The vertex will be 3,-4
The axis of symmetry will be x=3
The x intercept is (5,0) and (1,0)
the y intercept will be (0,5)
Step-by-step explanation:
i dont know the orientation
No, it is not.
If x+1 is a factor, x=-1 would be one of the zeros.
Plug x=-1 in the polynomial to see it is results in a 0:
2(-1)^3-9(-1)^2+13(-1)-6=-30≠0, therefore, x+1 is not a factor.
