Question

Given the function f(x) = 2|x + 6| – 4, for what values of x is f(x) = 6?
x = –1, x = 11
x = –1, x = -11
x = 14, x = –26
x = 26, x = –14

Answer 1

\[\large 6=2|x+6|-4\]
^Solve for x! Have fun!

Answer 2

|f(x)|=|-f(x)|=6
so following steve's input

f(x)=6
-f(x)=6

solve them both for x

Answer 3

i got -1 and -11 is that correct i think it is but i only have one chance

Answer 4

easy enough to check right?

Answer 5

\[2|-1+6|-4=65\]?

Answer 6

oops i mean 6?

Answer 7

and yes, you are right
