Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 2x - 1

g(x) = 2x + 1

<em>x</em> = -3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                                                                                                  f(g(-3))
  2. Substitute in <em>x</em> [Function g(x)]:                                                                         g(-3) = 2(-3) + 1
  3. Multiply:                                                                                                             g(-3) = -6 + 1
  4. Add:                                                                                                                   g(-3) = -5
  5. Rewrite:                                                                                                             f(-5)
  6. Substitute in <em>x</em> [Function f(x)]:                                                                           f(-5) = 2(-5) - 1
  7. Multiply:                                                                                                             f(-5) = -10 - 1
  8. Subtract:                                                                                                            f(-5) = -11

The graph has a y-intercept of 2 and is shifted to the right 6 from the parent function.

The parent function, y=√x, looks like a parabola laid on its side.  We generally only consider the positive square root unless told otherwise.  Since we have √(x-6) instead of just √x, the graph is shifted to the right 6 units.  The +2 at the end of the equation shifts the graph up 2.
