Answer:
(1, - 3 )
Step-by-step explanation:
Using the translation rule (x, y ) → (x + 2, y + 1 ), then
B(- 1, 2 ) → (- 1 + 2, 2 + 1) → (1, 3 )
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(1, 3 ) → (1, - 3 )
Answer:
The discriminant is equal to zero
Step-by-step explanation:
If x=6 is the only x-intercept of the graph of a quadratic equation, the it means the quadratic equation has a repeated root.
When a quadratic equation has a repeated root, it means its discriminant is zero.
This means that
