Question

What is the domain of the function f(x) = 2x2 + 7x - 4?

Answer 1

is there any reason what so ever that we CANT plug in each and every real number?

Answer 2

if f(x) is a polynomial then \(Domain = \mathbb{R}\)

Answer 3

A. (-,2)
B. (-,)
C. [4,)
D. [-4,)
these are the answers to chose from

Answer 4

none of those answers make sense

Answer 5

infinity

Answer 6

it didnt put it in when i copied it

Answer 7

ahh
so
\[(-\infty, \infty)=\mathbb{R}\]

Answer 8

the domain to any polynomial is all real numbers

Answer 9

i will make a bet
my bet is they are asking for the "range"
just a guess

Answer 10

They always ask this domain question with polynomials at least once. But I would not be surprised if you are right @satellite73

Answer 11

well the options for the range and the domain are both given, so ....lol
