Answer:
f(x)= 0.5^x has all real numbers as its domain
Step-by-step explanation:
We have three functions:
f(x)= 0.5^x while g(x) and p(x) are line segments
g(x) is a line segment which passes through the two points (-1.8,-3) and ( 1,3.8)
Its domain will be the ends points. so domain of the function g(x) will be [-1.8, 3.8] which is the subset of real numbers.
Like wise domain of function p(x) will be [1.7, 1], which is also the subset of real numbers.
But when we look at f(x) it has all the possible value of x. Thus we can say that f(x)= 0.5^x has all real numbers as its domain.
