graphing inequality where the variable is an exponent Reply to this Post

Hi. New to the site so maybe I missed this.

Trying to graph

y>=5^x-2

but the 2D inequality calculator doesn't seem to like this.

Also, I don't see variables as exponents in any of the examples.

Please help!

Good point. If you want an answer, I suggest you plot the function 5^x-2 and the upper part is where y is greater than the points on the curve. Use:

There, you can use variables as exponents without the kind of problem you are having.
