Question

find the domaing of the function f(x)=-9+4

Answer 1

it is not a function Ep4710_08. Coz there must be an x involved in the right side of the equation

Answer 2

it must look something like f(x)=9x-4

Answer 3

the answers should be the following [-9,00] or (-9,00), (-00,00), or (-00,4) or [00,4]

Answer 4

You can see that f is not a function of x. It is a constant. that means that for any x, you will only have a value for y. For example:
x=0, y=-5
x=2, y=-5
x=10, y=-5

so the domain of this function must be (-infinity, +infinity)

Answer 5

not sure of that my friend.

Answer 6

where did you get those answers?

Answer 7

ok. got it! you were right (-infinity, +infinity) thanks!
