This document summarizes a student's project on parabolas. It first describes solving a quadratic equation using graphical and formulaic methods and taking photos of parabolas from daily life. It then compares the two solution methods, noting the operations required for each. The document presents photos taken of parabolas in a paper holder, basketball court, smiley face, and waxing crescent moon. It concludes that parabolas can be seen throughout life in designs of objects and structures as well as in nature, and they have been useful in creating things throughout history.

2. Introduction
IN this project we had to do different things that had to do with parabolas.
Firstly we has to solve a quadratic equation using graphing method and
general formula to make a comparison between both methods. Afterwards
we have to take photographs of parabolas that we see in our daily life and
take two from worldwide things like monuments or other things.

4. Comparison
After solving the quadratic equation by both methods I could notice that while
in the general formula you have to do different operations like multiplying,
subtracting, divisions and square roots, in graphing methods you had to
replace certain values in the equation to get different coordinates that
would help you make the graph

Daily life parabolas
This photo is a
paper holder in
an x form. The
parabolas are
at the sides and
the top an
bottom.
The photo is a
basketball court. The
parabola is red zone
or the free throw
lane.
In this photo we can
see a smiley face. The
is found in the happy
mouth.
A waxing crecent is
shown on the image.
This phase of the moon
forms a parabola

6. ¿What utility does de us of parabolas have had?
Parabolas can be wee through all our life. They are not only seen in
mathematics. Parabolas are useful to design things like paper holder, courts,
logos of items. Parabolas haven been used through history in different ways,
for creating, or even, it can be seen in nature things.
