Question 60037This question is from textbook
: if the question is to A. graph y=[2x] by making a table of values. does that mean they want me to just make a table of values?? how would i do that? then it says to B. translate y=[2x] to graph y=[2x]+3. do i put this in my other chart from the previous thing??? would i graph it??? how would i graph it??? would i do the same thing to translate y=[2(x-1)]??? and y=[2(x-1)]+3???

You can put this solution on YOUR website! if the question is to A. graph y=[2x] by making a table of values.
If x=-2 y=[-4}=-4
If x=-1 y=[-2]=-2
If x=0 y=[0]=0
If x=1 y=[2]=2
If x=2 y=[4]=4
Plot these points on an xy coordinate system.
Hopefully you know the graph is a step-function.
Try some intermediate value lie -3/2, -1/2, 1/2, 3/2
so you can see where the steps are. Notice where
the change in values occurs; be sure you put the open
circle at the proper level and the solid circle at
the proper level.
--------------------------------
does that mean they want me to just make a table of values?? how would i do that? then it says to
-----------------
B. translate y=[2x] to graph y=[2x]+3.
All the y-values are increased by 3.
do i put this in my other chart from the previous thing???
No, you develop a separate chart.
would i graph it??? how would i graph it???
Graph it by plotting the new set of points. It should look just
like the 1st graph but raised up 3.
-------------------------
would i do the same thing to translate y=[2(x-1)]???
You take the 1st graph and move all the points 1 to the right.
--------------
and y=[2(x-1)]+3???
You take the graph you just completed and raise every point by 3.
Cheers,
Stan H.
