Question

What is the domain of the function below?

f(x) = x - 29.9
-29.9 < x < ∞
29.9 < x < ∞
-∞ < x < ∞
-∞ < x < 29.9

Answer 1

any line has a domain of all real numbers. In fact, any polynomial function has all real numbers domain

Answer 2

??

Answer 3

\(-\infty<x<\infty\) what does this one mean

Answer 4

infinity

Answer 5

all real numbers mean all the number line can be inputs for that function
there is no problem at all

Answer 6

I know that they are I'm asking what do they mean in words!
I'm giving you the answer in other words

Answer 7

The domain is the x-values

Answer 8

well can u tell me A B C or D

Answer 9

I can't tell you which one! you have to get it
how can we write all real number in set builder notation

Answer 10

look here at the number line

Answer 11

D

Answer 12

hmm that's not D
d is not all real number
it is only the number that are less than 29.9 ===> x<29.9

Answer 13

@SwaqqOut_KID1
Do you know what choice D means?
It means that x can be any real number less than 29.9

Answer 14

oops i meant 2 put B lol

Answer 15

B is not good too
it mean all numbers that greater than -29.9

Answer 16

are*

Answer 17

OO

Answer 18

actually, you should properly graph the line in the coordinate plane with the slope and y intercept.

Answer 19

Look at the number coordonite plane @Cosmichaotic drew
all real number means all the line

Answer 20

Well, that's what I think.

Answer 21

I don't think there is a need for graph of the line
I'm positive it would confuse the poster more than just a number line
