Answer:
y = (1/3)x - 4
Step-by-step explanation:
Notice that the graph crosses the y-axis at (0, -4). The y-intercept is thus 4, which we often call "b."
If we start at (0, -4) and move to the right along the graph, we see that the first point at which both the change in x and the change in y are integers is (3, -3).
As we go from (0, -4) to (3, -3), x increases by 3 and y increases by 1.
We can then conclude that the slope, m, of this line is
m = rise / run = 1 / 3.
Substituting b = -4 and m = 1/3 into the slope-intercept form of the equation of a straight line, we get:
y = (1/3)x - 4
Translation by h right and k up: f(x-h)+k.
Vertically scale by k and reflect across the x-axis: -k·f(x).
After the translation, your function is
f(x) = (x-2.5)² -7
After the scaling and reflection, your function is
f(x) = (-2/5)((x -2.5)² -7)
