Question Details:

The graph of f(x)=x is sketched in black and it had undergone a series of translations to graphs of functions f_1 sketched in green, f_2 sketched in blue, and f_3 sketched in red. f\rightarrow f_1\rightarrow f_2\rightarrow f_3. Use the translation rule and f(x)=x to identify the function f_1(x);

f_1(x)=

Use the translation rule and f_1(x) to identify the function f_2(x);

f_2(x)=

Use the translation rule and f_2(x) to identify the function f_3(x);

f_3(x)=

Response Details:
f1(x)= (x-6)^2
f2(x)=-(x-6)^2
f3(x)=-(x-6)^2 + 6
 
 
lets say you are translating t spaces, and if the translation is to the right then you replace x with x-t. if it is moving up then you just + t to the original equation
