Best ResponseYou've already chosen the best response.0Just calculate some function values at some points x and connect them.

Best ResponseYou've already chosen the best response.0Oh well. Then you do it the following way: 1. You draw x and yaxis 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 xvalues, 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.

Best ResponseYou've already chosen the best response.0try making a table x y 2 ? 0 ? 2 ? the y values you get by putting the x value into the equation 2x+2 +8 to get more points add more xvalues to the table

Best ResponseYou've already chosen the best response.0and does it open up or down and is it narrow or wider?

Best ResponseYou've already chosen the best response.0If you can't imagine it, you have to draw it alongside with the function you want to compare it to.

Best ResponseYou've already chosen the best response.0Of course there is also software that can do it for you. They are called CAS. You could even use WolframAlpha online.
