# Thread: How in the heck do I graph this?!

1. ## How in the heck do I graph this?!

I have no clue how to graph this in a workable fashion.

$\displaystyle y=3^x$.

I do know how to graph other equations,(1) put the question into standard form if it isn't already, (2)replace the x or y variable(usually the x gets replaced), (3)work the equation to get y, (4)graph the point, (5)repeat steps 2-4 3 to 6 times, (6) connect the dots.

My problem is that the graph I am working with is fairly small, so the answers are either to high to graph or are decimals meaning that any attempt at accuracy is difficult.

Thank you!

You can compress the y axis,
or use log-linear graph paper.

Just one question though:
Just note the adjusted scale to compress the y axis,right?

I don't think I can use log-linear graph as I am required to give a (x,y) graph as my answer.

4. Yes, in that case just make the difference between units smaller on the y-axis.
This will allow you to draw a graph that looks similar to the .jpg file.
Decide on the highest value of x you want to use, say x=5.

Then since x=5, $\displaystyle 3^x=3^5=243$

so scale the y-axis from 0 to 300, using 1 y unit = 100
or something similar.

5. Many gracious thanks Archie!

Could I ask a side question?

What is the best method to manually graph an ellipse?

6. Hi Mathblaster47,

maybe the draughtsman's method at the following link would be most practical.
