Answer:
The correct option is C.
Step-by-step explanation:
If a parabola is defined as
.... (1)
then the vertex of the parabola is
The given function is
.... (2)
From (1) and (2) it is clear that
Substitute a=-2 and b=4 in the above equation.
The value of h is 1.
substitute h=1 in function (2).
The vertex of the function is (1,-5). Therefore the correct option is C.
A quadratic equation has exactly one real number solution.
For any quadratic equation the discriminant D is 
When discriminant D> 0 then there will be 2 real solutions
When discriminant D= 0 then there will be 1 real solution
When discriminant D< 0 then there will be 2 complex solutions
Question says 'A quadratic equation has exactly one real number solution'
So Discriminant D =0
Answer:
5,0
Step-by-step explanation:
you move point b to the right 1 and down 2 to get your new b prime
