It's already a square; we don't need to add anything to complete the square.
That's a vertex at x = -1. The corresponding y is y=0.
Answer: Vertex at (-1,0)
As for the other questions cut off there, the axis is the vertical line x = -1 and the range is y ≥ 0.
Using translations, it is found that the equation the represents the graphed function is:
, given by option C.
----------------------------------
- The parent function is
.
- <u>As x increases, it's value increases. In the graph, as x increases, it decreases</u>, thus it was multiplied by -1, that is,
.
- The parent function is defined for
, and the same is valid for the function in the graph, thus we have
and not
.
- The initial value of the parent function is
, here it is
, thus it was shifted down 3 units, that is,
, and the correct option is C.
