Answer:
Step-by-step explanation:
A polynomial function is given by the form:
Where a is the leading coefficient, and <em>p</em> and <em>q</em> are the roots (more can be added if necessary).
Our zeros are 3 and (-2 + 2i).
And our leading coefficient <em>a </em>= 1.
Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.
So, by substitution, we acquire:
Simplify:
Expand the second and third factors:
Therefore, our polynomial function of least degree and the given zeros will be:
Answer:
1 is the answer see attached
Step-by-step explanation:
1 is a function
2 is not a function as it is x+y
3 is a boundary function of how many parameters
4 is not a function as such parameters are too long however many of the decimals divide into each other and appear functional.
