Question

Which of the following points lies on the graph of y = x^2 - 2x + 6?
(-3, 21)
(-2, 0)
(-1, 10)

Answer 1

Answer:

(-3,21) should be the answer

Answer 2

Option 1 - (-3,21)

Step-by-step explanation:

To find : Which of the following points lies on the graph of $y = x^2-2x + 6$ ?

Solution :

Equation $y = x^2-2x + 6$

To get the points lie on graph it satisfy the equation,

1) (-3,21)

Put x=-3,

$y = (-3)^2-2(-3)+ 6$

$y = 9+6+ 6$

$y =21$

The point satisfy the equation so it lies.

2) (-2,0)

Put x=-2,

$y = (-2)^2-2(-2)+ 6$

$y = 4+4+ 6$

$y =14$

The point does not satisfy the equation so the point not lie.

3) (-1,10)

Put x=-1,

$y = (-1)^2-2(-1)+ 6$

$y = 1+2+ 6$

$y =9$

The point does not satisfy the equation so the point not lie.

Therefore, the correct option is 1.
