If f(x) = absolute valve of x-2 is a function, then find f(2), f(x+2) & f(-4)?

Question

If f(x) = absolute valve of x-2 is a function, then find f(2), f(x+2) & f(-4)?

Answer 1

f(2)= 0

f(x+2)= x

f(-4)= 6

Answer 2

0

|x|

6

im in 9th grade. thats how i do functions idk if that is correct though. i did them in my head

i guess it is rite

Answer 3

So f(x)=abs(x-2)

f(2) = abs(2-2) = abs(0) = 0

f(x+2) = abs (x+2-2) = abs(x)

f(-4) = abs(-4-2) = abs(-6) = 6
