Math Problem Statement

use translations to graph the given functions g(x) = square root of x + 5

Solution

The function you're asking to graph is g(x)=x+5g(x) = \sqrt{x + 5}.

To understand the graph of this function, we can break it down in terms of transformations from the basic square root function f(x)=xf(x) = \sqrt{x}. Here's how this transformation works:

Steps to Graph:

  1. Start with the basic graph of f(x)=xf(x) = \sqrt{x}:

    • The graph of f(x)=xf(x) = \sqrt{x} starts at the point (0,0)(0, 0) and increases slowly as xx increases.
  2. Apply the translation:

    • The expression x+5\sqrt{x + 5} indicates a left shift by 5 units.
    • To see this more clearly: g(x)=x+5g(x) = \sqrt{x + 5} is equivalent to f(x)=xf(x) = \sqrt{x}, but with the input shifted 5 units to the left. So, instead of starting at (0,0)(0, 0), the graph of g(x)g(x) will start at (5,0)(-5, 0).
  3. Behavior of the graph:

    • For g(x)=x+5g(x) = \sqrt{x + 5}, the domain is x5x \geq -5, since the square root function is only defined for non-negative values inside the radical.

Important Points:

  • The graph starts at (5,0)(-5, 0).
  • The graph follows the shape of the basic square root curve but is shifted left by 5 units.

Now, I’ll summarize:

  • The general shape is still a curve that increases as xx increases.
  • The graph has no values for x<5x < -5.

Would you like me to generate a visual graph of this function?
