The graph below shows three functions:

Graph of function f of x is a line segment connecting points negative 1, 11 and 4, negative 3. Graph of function g of x is a line segment with holes at the endpoints connecting negative 2, negative 4 and 0.5, 10. Graph of p of x equals 8 to the power of x.

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)

I think you'd find this problem to be a lot easier if you'd first graph both functions.

Also, please write "negative 1, 11" as (-1,11).  Easier to work with!

domain are the x-values
which graph looks like it uses all x values?
any idea ?

phi · Answer

you can use your common sense on this:  two of the functions don't go "forever" so they can't have "all x's" as their domain.

so is it p(x)
