Graph of function f of x equals 2 to the power of negative x. Graph of function g of x equals 5 to the power of x. Graph of p of x is a line segment connecting points negative 1, negative 3 and 2, 12.
Which function has all real numbers as its domain?
Only f(x)
Both g(x) and p(x)
Both f(x) and g(x)
Only p(x)

Best ResponseYou've already chosen the best response.1let's just say you have h(x) = x h(x) has domain of all real number because you can plug any values in h(x)

Best ResponseYou've already chosen the best response.1You can see that p(x) only goes from about 1 to 2 in xcoordinate, right?

Best ResponseYou've already chosen the best response.1yeah there are ends. So domain of p(x) is not all real number. Does that make sense?

Best ResponseYou've already chosen the best response.1p(3) is not definied (has no value) because 3 is not in domain of p(x)

Best ResponseYou've already chosen the best response.1okay what about f(x) and g(x)?

Best ResponseYou've already chosen the best response.1\(f(x) = 2^{x}\) \(g(x)=5^x\) Is there any x value you cannot plug in?

Best ResponseYou've already chosen the best response.1well f(2) = \(2^{(2)} = 2^2 = 4\) So 2 is in domain of f(x). same goes for g(x)

Best ResponseYou've already chosen the best response.1you can think of it as "machine"dw:1438987847196:dw like f(x) would "change" 2 to any number, depend on what f(x) is. Make sense so far?

Best ResponseYou've already chosen the best response.1domain is basically like what number you can put into machine

Best ResponseYou've already chosen the best response.1if domain is 1 to 3, you can only put in any number between 1 to 3. No 5 or something

Best ResponseYou've already chosen the best response.1If domain is real number, that means you can put in ANY (real) number.

Best ResponseYou've already chosen the best response.0so i can say any number

Best ResponseYou've already chosen the best response.1well, can you plug any number in f(x) and g(x)? That's the question

geerky42

Best ResponseYou've already chosen the best response.1ok so domain of f(x) and g(x) is real number.
