Question

What is the domain of the function below?

f(x) = x - 2.9

Answer 1

all real numbers

Answer 2

how did you get that?

Answer 3

because all you have in terms of the variable is "x". there is noting affecting the variable, (division, square root, etc.)

Answer 4

therefore, the variable is able to be any number possible and then have 2.9 subtracted from it.

Answer 5

For example, x=5--> y=2.1 x=0-->y=-2.9 x=-0.5-->y=-3.4

Answer 6

does that make sense?
