Finding intersections

Lee Fisher shared this question 3 years ago
Needs Answer

Hi - I'm solving exponential equations with an 'technology tools' approach. We graphed e^x, we graphed y=100, we asked for an intersection but we were declined.

Check this out - why is my point undefined when y=97, or when y = 100, and some other values but otherwise its all good?

Also, is there a command I can use with 'solve' to guarantee a decimal answer?

Thanks!

Salut Aileen!

Hmm, for me it looks ok.

Ok, now I can confirm the problem.

GG 5.0.536 and Win 10 Pro.

The Android-App doesn't have the issue.

I guess that in the meanwhile, as a workaround, you can create the point (ln(a),a)
