Answer:
B. (x-2)^2=12
Step-by-step explanation:
The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.
There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.
x^2 -4x +2 = 10 . . . . . . . given
x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)
(x -2)^2 = 12 . . . . . . . . . write as a square
Answer:
(2,20)
Step-by-step explanation:
The given function is

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;
For the first point we substitute x=3 and f(x)=250

This is true.
For the second point (2,20), we put x=2 and y=20 to get:

This is false, hence (2,20) does not lie on this curve.
For (1,10), we have:

This is also true
Finally for (2,50), we have;

This is also true.
