What transformation is made from f(x) → f(-x)

reflection over y-axis

Step-by-step explanation:

The x value for point B that is located ¼ the distance from point A to point C is -0.75. Point A which is (0,4) and point C (-3,5) are the given values in the problem. It is assumed that point A is 75% while point C is 25%.
To determine the x-value, 
¼(-3) + ¾(0) = -¾ = -0.75
