ik the answer is Y=(X+2)^(2)-3 I just don't know how to solve it

y=−(x−2)2−3

Answer 1

To determine which equation best represents the graph shown, we can analyze the mathematical transformations necessary to produce the graph.

First, let's start with the basic graph of y = x^2. This is a U-shaped graph that opens upwards and has the vertex at the origin (0, 0).

Now, let's go through each transformation step:

1. The graph is multiplied by -1: This reflects the graph across the x-axis, so the U-shape becomes an inverted U-shape.

2. The graph is shifted 2 units to the right: This means every x-value is increased by 2, shifting the entire graph to the right. The vertex, which was at (0, 0), will now be at (2, 0).

3. The graph is shifted 3 units downwards: This means every y-value is decreased by 3, shifting the entire graph downwards. The vertex, which was at (2, 0), will now be at (2, -3).

Putting all these transformations together, we have:
y = -(x-2)^2 - 3

This equation satisfies all the transformations described above and matches the graph shown.
