In composite function gof, what is the range and the domain?

Answer 1

QuantumTorch: And the domain is what f(x) can equal. The range is what g(f(x)) can equal 2:03 pm

Answer 2

the domain is whatever is legal to enter in

the range is whatever gets returned

Answer 3

hah...your 2 hours away from me :)

Answer 4

Lol

Answer 5

the domain is actually whatever is legal for f(x) and whatever is legal for g(x)

Answer 6

does no good for f(x) to illegate g(x)

Answer 7

so basically in in function gof, range will be domain of g?

Answer 8

no; range is whatever gets returned as a value from the inputs;

think of domain as whatever you put into the oven

and

think of range as what you take out of the oven.

Answer 9

the 2 are related, but not the same unless the oven function is set to inverseify

Answer 10

yeah, just what I said P

Answer 11

qt, you gotta get a new pic...that ones just so darn distracting ;)

Answer 12

ok now i get it, so the range will be range of f, right?

Answer 13

Haha I can't on the iPad.

Answer 14

(Domain of f(x))-----(f(x))-----(Range of F(x))------>>

----(Range of f(x) = Domain of g(x))-----g(x)------->>

------->>(Range of gof)!

Answer 15

green= Domain of f(x) ; yellow = Range of f(x)

yellow = Domain of g(x) ; red = range of (gof)(x)
