Answer:  [D]:  " - i " .

Step-by-step explanation:

Note:  " i ³ = \sqrt{-1} .

\sqrt{-1} * \sqrt{-1} * \sqrt{-1} = [ \sqrt{-1} * \sqrt{-1} ] * \sqrt{-1}

                                                             =  {-1}   *  \sqrt{-1}  

                                                             =  -1 \sqrt{-1}
                                                             =    - \sqrt{-1} ;

                                           →  which corresponds to:

                        Answer choice:  [D]:  " - i " .

The graphs below have the same shape. What is the equation of the blue graph?
postnew [5]

Answer:

<h2>C. G(x) = (x - 1)² - 3</h2>

Step-by-step explanation:

f(x) + n - shift the graph of f(x) n units up

f(x) - n - shift the graph of f(x) n units down

f(x - n) - shift the graph of f(x) n units to the right

f(x + n) - shift the graph of f(x) n units to the left

===================================

Look at the picture.

The graph of F(x) shifted 1 unit to the right and 3 units down.

Therefore the equation of the function G(x) is

G(x)=(x-1)^2-3
