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

Did you graph it?
lol no idk how
Just calculate some function values at some points x and connect them.
Not the answer you are looking for? Search for more explanations.
i still dk how to do that
can you help me
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
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
so the vertex is -2,8
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.
