### The identification of the Polynomial functions ?

I am confusing about how can we identify whether the function is in the polynomial form or not.
For example i have : x^5 - 1 and 25 . Are they the polynomial functions and i need to be explained ?

### Re: The identification of the Polynomial functions ?

I got it. Thank you so much! :wink: . But i just want to ask 1 question about the polynomial : Is any number like 25, 2, 4, the polynomial function, and if so, what is the degree of these? Is that a "0" ? Thank again ! Also i would like to ask "What is the real number and how can we k...

### Write the quadratic function from the table of values

Can some one tell me how to find the vertex and create a "Quadratic function" in "Vertex form" from this table of value :

(-3,-0.5) (-2.5, -3) (-2, -4.5) (-1.5, -5) (-1, -4.5) -0.5, -3) and (0, -0.5)

And after we have a vertex , determine whether it is a max or a min ?

Thanks!

### Finding vertex of quadratic is same to of linear functions ?

Thank you for your answering! I got the second part (Whether the vertex is max or min), but i still be stuck in part that how can i figure out the coordinates of the vertex in these seven points, will the vertex be the middle point ? If so, how can i find the vertex when the number of points that ar...

### How to factor the quadratic function from the general form!

I have a question about how can i use the "rectangular diagram" to convert the general form of quadratic function to the square (Factor the quadratic function) : Actually, i don't know how to find the middle term in the trinomial. For instant : x^2 - 22x + 121 so we have http://farm4.stati...

### Identify the equation form of the problem !

Can some one tell me that :How can i identify the form of polynomial functions in different cases . For example, from the table of value : (1, 38.4) , (1.5, 30) , (2, 19.6) , (2.5 , 7.2) How can i know that the function that model this table of value is which one in polynomial function to know the g...

### Re: Identify the equation form of the problem !

I am getting this math class without the teaching or explaining of the teachers, I just take the books and read them, then i do my homeworks that are given by the teacher as much as i can. Unfortunately, in my book, it doesn't have the way to solve this problem. ^^! Sorry about that. But i guess tha...

### Re: How to factor the quadratic function from the general form!

Thank you for your answering, but it is still difficult to know what are the factor of some vast number. Here is the other way to find the middle term of trinomial function (Is my problem is to find the letter "a" and "b"). We have : x^2 - 22x + 121 = y First Step : Identify the ...
