Question

Which point lies on the graph of f(x) = -2(x + 3) – 5 A) (-6,1) B) (-6,-8) C) (6,-13) D) (6,-4)

Answer 1

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 :)
