I don't know if I'm correct, I'm guessing... 30
The “1/2” caused the parabola to be vertically compressed meaning it got wider.
and the “-2” caused the parabola to move 2 units to the right
Therefore the correct answer should be C.
(-4,4) (2,1)
gradient = (1-4)/(2--4) = -1/2
y = mx + c
y = -1/2x + c
Replace point (2,1) in the equation
1=-1/2(2) +c
c = 2
Equation : y = -1/2x + 2
y-2 = -1/2x
Answer is C.
