The function f(x)=2/3x-4 was replaced with f(x+k)=2/3x-6 what is the value of k

The given function was replaced with then the value of k is -3

that is k=-3.

Step-by-step explanation:

The given function is

and when x=x+k then

Now to find the value of k:

Put x=x+k in the function f(x)

Now comparing equations (2) and (3) we get

Therefore k=-3

Therefore the given function was replaced with   then the value of k is -3

that is k=-3.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
