Question

is this equation -5x + 1/3x a polynomial ?

Answer 1

you'll have to refresh my memory. If the x is in the denom, doesn't that mean that there is a value for x where the function is undefined? And I'm pretty sure that polynomial function are define for all real numbers, so using that *very* sketchy logic, I'd say it isn't.

Answer 2

unless that is really a (1/3)x, then in that case it is defined for all real values of x, and then I'd call it polynomial.

Answer 3

so is not right i think the same

Answer 4

i have another question if this one to

Answer 5

which one?

Answer 6

i need to know if its andif it s what is the variable term and degree

Answer 7

well, if I can decipher your...drawing...then it looks like you've got some negative exponents on those variables. So it is really 6/[(x^3)(y)[ <--the x and the y are in the denominator

Answer 8

which means not polynomial

Answer 9

yeah it have negative

Answer 10

right, so we know that there are values for x and y that would make that function undefined.

Answer 11

did that answer your question?
