Answer:

Irrational number, any real number that cannot be expressed as the quotient of two integers. For example, there is no number among integers and fractions that equals the square root of 2. ... Each irrational number can be expressed as an infinite decimal expansion with no regularly repeating digit or group of digits.

The graph below shows three functions: Graph of function f of x equals 0.5 to the power x. Graph of function g of x is a line se

Phantasy [73]

Answer: f(x)= $0.5^x$ has all real value as its domain.

Explanation: since, we have three functions f(x)= $0.5^x$ ,

while g(x) and p(x) are line segments.

Now, g(x) is a function by a line segment which passes through two points (-1.8,-3) and ( 1,3.8).

Thus it is clear that 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 set (R).

Similarly, domain of function p(x) will be [1.7, 1], which is also the subset of R.

But, when we talk about f(x) it contains all the possible value of x. Thus we can say that $f(x)= 0.5^x$ has R as its domain.
