There's no base.

A tunnel in parabolic shape is defined by the x^2-16y=0 (dimensions measured in feet). What is its width at the base?
~~~~~~~~~~~~~~~~~
In Math, if the opposite is not pointed explicitly, y-axis in a coordinate plane, by default, is directed vertically up.
In accordance with this conception, your parabolic tunnel is upside down.
If you got this problem from your teacher/professor, then please inform him/(her) about it.
If you copy-pasted it from some web-site, please let them know about this hitch.
If it is written in your textbook, then inform the author and/or the publishing company.
It may happen that in response they will offer a position of a proof-reading editor to you, for attentive reading.
If you created it on your own, then throw it to closest garbage bin silently, without making much noise,
and do not tell anybody about it. Also, do not spread it in the Internet.
If you know personally an individual who created this "problem", then show him (or her) this my post,
or re-post to him (to her).
Urgent measures should be taken ( ! )
