Question

what is the domain for g(x) = 128x

Answer 1

this is a linear equation and it's a polynomial

both of which have the domain of the set of all real numbers

Answer 2

this is because you can plug any number you want in for x and you'll always get some real number result out for g(x)

Answer 3

can you give me an example? i'm so lost on this stuff. :/

Answer 4

think of any number you want

Answer 5

um 10

Answer 6

then plug it in for x and you'll find that the result is some real number

Answer 7

so pretty much the domain is all real numbers?

Answer 8

so x = 10

g(x) = 128x

g(10) = 128*10

g(10) = 1280

notice how we got a real number result

Answer 9

yes it is

Answer 10

yes

Answer 11

thank you!

Answer 12

you're welcome
