Math Problem Statement

Begin by graphing the standard square root function f(x) = √x. Then use transformations of this graph to graph the given function h(x) = √(x + 2) + 1.

Solution

The function given is h(x)=x+2+1h(x) = \sqrt{x + 2} + 1, and we need to graph this using transformations of the standard square root function f(x)=xf(x) = \sqrt{x}.

Steps to graph the transformation:

  1. Start with the graph of f(x)=xf(x) = \sqrt{x}. This is the basic square root function, which begins at the origin (0, 0) and increases to the right.

  2. Horizontal shift: The term +2+2 inside the square root function means a shift 2 units to the left. So, the starting point for x+2\sqrt{x + 2} will be at (2,0)(-2, 0).

  3. Vertical shift: The +1+1 outside the square root indicates a shift 1 unit upwards. This will move the entire graph of x+2\sqrt{x + 2} one unit higher.

Thus, the graph of h(x)=x+2+1h(x) = \sqrt{x + 2} + 1 will start at (2,1)(-2, 1), and will follow the typical shape of the square root graph, shifted accordingly.

Now, let's compare this with the provided options in the image. Based on the transformations, the graph that best matches this description is the one that starts at (2,1)(-2, 1), with the familiar square root shape.

Tip: When identifying transformations, always look for changes inside the function (affecting xx) for horizontal shifts and changes outside the function (affecting the whole graph vertically).
