Precalculus 11

1. Birthday
Polynomial
Project
By: Nathanael

2. Recently,
we learnt about the
Polynomial
Functions
!"="3+2x-1

3. And
We have an
INCREDIBLE
idea

4. How about
mixing
the functions
and my birthday date
together?!

5. First,
Write down my birthday date.
18 08 2006

6. Second,
write it in order
18 08 2006

7. 18-08-2006
DateMonthYear
Second,
write it in order

8. 18082006
Second,
write it in order

9. Third,
Create a polynomial function
f(x)=1x8+8x7+8x5+2x4+6

10. Fourth,
Go to the
desmos

11. Fifth
Analyzation
Find out:
a. x-intercept
b. y-intercept
c. end behaviour
d. points

12. a.x-intercept
(-8.118,0)
(-0.882,0)
Fifth
Analyzation

13. b. y-intercept
(0,6)
Fifth
Analyzation

14. c. End behaviour
The graph
opens upward
and has an
increasing trend
Fifth
Analyzation

15. For the
End Behaviour…
Why it is
“open upward ”
and
“increasing trend”?!

16. The overall trend of this function is
that it
Opens Up
In part, it is an
odd polynomial
with
positive leading coefficients

17. Fifth
Analyzation
d. Points
