Answer:   [tex]y=\sqrt{x-3}-5[/tex]

Step-by-step explanation:

The vertex form of a square root equation is: [tex]y=a\sqrt{x-h}+k[/tex] where

  • a is the vertical stretch
  • h is the horizontal shift (positive is right, negative is left)
  • k is the vertical shift (positive is up, negative is down)

Input: h = 3 (3 units right) and k = -5 (5 units down) into the vertex form:

[tex]y=\sqrt{x-(3)}+(-5)\\\\y=\sqrt{x-3}-5[/tex]

The resulting equation is: [tex]h(x) = \sqrt{x - 3} - 5[/tex]

-------------------------------

This question is solved using the translation concept.

  • Translating a function f(x) a units to the right is the same as finding f(x - a).
  • Translating a function f(x) a units down is the same as finding f(x) - a.

-------------------------------

Original function:

[tex]f(x) = \sqrt{x}[/tex]

-------------------------------

Translated 3 units to the right

This is f(x - 3), so:

[tex]g(x) = f(x - 3) = \sqrt{x - 3}[/tex]

-------------------------------

Translating 5 units down

This is g(x) - 5, so:

[tex]h(x) = g(x) - 5 = \sqrt{x - 3} - 5[/tex]

Which is the resulting equation.
