how do you find the domain?

ramen:

Is there a specific question that this applies to?

mathclass:

ya

ramen:

Can you post it plz?

mathclass:

justus:

The domain is all the x's and the range is all the y's.

ramen:

Do you think age would represent y or x on a graph?

ramen:

*or table

mathclass:

y

mathclass:

wait i think x

darkknight:

consider age to be x and height to be y Now the domain which is the interval that their ages extend upon is from 6 to 13 years old this is the domain The range which the interval that their heights extend from is from 110c (lowest) to 156 cm (highest) this is the range

mathclass:

so 110-156

darkknight:

thats the range (height) yes

mathclass:

and the domain would be 6 and 13

darkknight:

yes, (the age)

mathclass:

ok thank you

darkknight:

np

JosephGunnels:

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
