If f(x) is a function whose domain is [-1, 9], and g(x) = f(2x), then the domain of g(x) is an interval of what width?

f (2x)  means  that  the original function is  horizontally compressed by a factor of  2

 

So....the original  domain  has a width of 10......the new domain has a width of 5

 

cool cool cool
