Question 56415: The homework asks me to "graph each function on a seperate piece of graph paper", and then proceeds to list different equations that will result in step graphs. I am able to solve the equations, but am unsure of how to graph my results. For example:
1. y=[x+3]
I set y=0...
0=x+3
-3=[x]
0+y
And then plugged in a point for x in order to find another ordered pair for the step graph...
y=[2+3]
y=5
x=2
My question is, essentially, how do i graph these equations in a "step graph"??
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! y=[x+3]
If your brackets mean "absolute value" the
graph is not a step function. Step functions
have a discontinuous pattern, like a step.
Your function looks like the letter V.
To see what it looks like plot a few points:
y=|x+3|
If x=-5 you get y=|-5+3|=2 giving point (-5,2)
If x=-4 you get y=|-4+3|=1 giving point (-4,1)
If x=-3 you get y=0 giving point (-3,0)
If x=-2 then y=|1|=1 giving point (-2,1)
If x=-1 then y=|2|=2 giving point (-1.2)
If x=0 you get point(0,3)
Plot these point and you will see the V shape
of the graph.
Cheers,
Stan H.
