The identification of the Polynomial functions ?  TOPIC_SOLVED

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 ?
Please help me !Thanks!

Re: The identification of the Polynomial functions ?  TOPIC_SOLVED

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  TOPIC_SOLVED

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 ?  TOPIC_SOLVED

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...

Identify the equation form of the problem !  TOPIC_SOLVED

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 !  TOPIC_SOLVED

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: Identify the equation form of the problem !  TOPIC_SOLVED

When i tried to find the degree of this, i also get 3, so this problem is probably the cubic function. But it is wrong, because i did see the answer in my teacher book. They state that it is degree of 2, and it is a quadratic function. So, I am confusing! :oops: And when i assume that it is a quadra...
