graphing an equation: y = 4 / (2x + 1)

[sclang63]

the instructions are simply, "graph the equation". I'm trying to manipulate this equation into a form that makes that possible.

y=4/(2x+1)

Why do you think it is not possible in the present form?

Do you know what yould the graph of

\(\displaystyle y \, = \, \frac{1}{x}\)

look like.

The given function is just transformed (x-y shift & contraction/expansion) of the above.

Another way:

First find assymptotes, roots, maxima, minima, inflection point, etc. of the given function.

Then just make chart according to the domain and ranges that you have found above.
