Tell weather the graph opens up or down Identify the vertx tell if the graph is wider or narrower or the same as the graph of Y =|X| f(x)=2| x+2| +8

    Just calculate some function values at some points x and connect them.

    Oh well. Then you do it the following way: 1. You draw x- and y-axis orthogonal to each other. 2. make ticks for some multiples of a unit at both axis. So for example at -5, -4, -3, ..., 5. Just how much space you think you will need. 3. For each of those x-values, and maybe some in between you calculate f(x) 4. At the point (x, f(x)) in your coordinate system you make a dot / cross 5. You connect the points from left to right.

    try making a table x y -2 ? 0 ? 2 ? the y values you get by putting the x value into the equation 2|x+2| +8 to get more points add more x-values to the table

    and does it open up or down and is it narrow or wider?

    If you can't imagine it, you have to draw it alongside with the function you want to compare it to.

    Of course there is also software that can do it for you. They are called CAS. You could even use WolframAlpha online.
