Answer:
Graph A
So it has two distinct real roots.
Graph B
It has one repeated real root
Graph C
So it has two complex roots.
Graph D
One real root and one complex root
Step-by-step explanation:
For graph A
The value of the roots is x= 1 and x= 3
And the minimum value = -3
It's a positive graph
So it has two distinct real roots.
For graph B
The value of the roots is x = 2 and x= 2
That is x= 2 twice
Has a maximum value of 0
It's an inverse graph
It has one repeated real root
For graph C
It's a positive graph but on the negative of x
Has a minimum value of 1
It didn't touch x at y = 0
And it's root will be negative
So it has two complex roots.
For Graph D
Value of the roots is x= 2 and x= -2
It's a positive graph
Minimum value of -4
One real root and one complex root
