What is the equation of the translated function, g(x), if
f(x) = x-?
g(x) = (x + 5)2 + 2
g(x) = (x + 2)2 + 5
g(x) = (x - 2)2 + 5
g(x) = (x – 5)2 + 2

Answer: Last option.

Step-by-step explanation:

The complete question is: "What is the equation of the translated function, [tex]g(x)[/tex] if [tex]f(x) = x^2[/tex]?

The missing graph is attached.

Below are shown some transformations for a function [tex]f(x)[/tex] :

1. If  [tex]f(x)+k[/tex] the function is translated "k" units up.

2. If  [tex]f(x)-k[/tex] the function is translated "k" units down.

3. If  [tex]f(x+k)[/tex] the function is translated "k" units to the left.

4. If [tex]f(x-k)[/tex] the function is translated "k" units to the right.

In this case, you can observe in the graph that the vertex of the parabola (function [tex]f(x)[/tex]) is at the following point:

 [tex](0,0)[/tex]

And the vertex of the translated parabola (function [tex]g(x)[/tex]) is at this point:

[tex](5,2)[/tex]

Therefore, based on the transformations explained before, you can identify that the function [tex]g(x)[/tex] is obtained by translating the function [tex]f(x)[/tex] 5 units to the right and 2 units up.

Then, the equation of the function [tex]g(x)[/tex] is:

[tex]g(x)=(x-5)^2+2[/tex]
