Math Problem Statement

Write the expression for the transformation of the square root function shown below.

Solution

The given graph depicts a transformation of the basic square root function y=xy = \sqrt{x}.

Let's break down the transformation:

  1. Horizontal Shift: The graph appears to be shifted to the left, as the starting point (where y=0y = 0) seems to occur at x=2x = -2. This indicates a horizontal shift by 2 units to the left, which suggests a transformation of x+2\sqrt{x+2}.

  2. Vertical Shift: The graph's starting point (vertex) is also raised to y=2y = 2, indicating a vertical shift 2 units up. This means we add 2 to the entire function.

  3. No Reflection or Stretching: The shape of the graph suggests that there are no reflections (no negative signs) or vertical stretches/compressions applied.

Thus, the transformed function can be written as:

y=x+2+2y = \sqrt{x + 2} + 2

Would you like more details, or do you have any questions?

Here are some related questions you might want to explore:

  1. How do horizontal shifts affect the square root function?
  2. What happens to the graph of y=xy = \sqrt{x} if we apply a vertical reflection?
  3. Can the transformation include both horizontal and vertical stretching or compressing?
  4. How does a vertical shift affect the domain and range of the square root function?
  5. What would the equation look like if there were a vertical stretch applied?

Tip: When analyzing graph transformations, always check for horizontal and vertical shifts, stretches/compressions, and reflections. Each of these affects the graph in predictable ways.
