first you'd work around the parenthesis, getting you a reduced problem of -2x-6-5.
combine like terms to receive -2x-11
now treat the f(x) as Y and you'll get y=-2x-11; toss it onto a graph and plot the individual points (your answer options)
all points except for A do not touch the line, resulting in your answer to be letter A!
hope this helps :)
