#1,2,4: translation up or down is done by adding or subtracting from y.
If y = f(x)
then y = f(x) +3 shifts the graph up.
#3: reflection through the x-axis is done by changing the sign of y. What was above goes below, etc.
y = -f(x) reflects f(x) through the x-axis.
#5: replacing x with (x-h) shifts the graph to the right.
replacing x by (x+h) shifts to the left by h.
There are lots of good online graphing sites.
desmos and wolframalpha come to mind.
Enter your functions and see what happens.
