<h3>Function Notation</h3>
The function is given as:

The interpretation when Steven is asked to calculate Blue(s + h) is that:
Steven is asked to find the output of the function Blue, when the input is s + h
So, we have:

Evaluate the exponent

Expand the bracket

So, the correct work is:

<h3>Simplifying Difference Quotient</h3>
In (a), we have:


The difference quotient is represented as:

So, we have:

Evaluate the like terms

Evaluate the quotient

Hence, the correct work is:

Answer:
The rational numbers are
and the irrational functions are
.
Step-by-step explanation:
A rational number can be expressed in the form of
, where p and q are integers and q is not equal to 0. For example
.
An irrational function can not be expressed in the form of
, where p and q are integers and q is not equal to 0. For example
.
If any number is multiplied by a irrational number then the resultant number is an irrational number.
By the above definition we can conclude that:
The number
is a rational number.

Therefore
is an irrational number.

Therefore 6.25 is a rational number.

Therefore 0.01045 is a rational number.

The number
is a rational number.

The number
is an irrational number.

Therefore
is an irrational number. The numbers with recursive bar are always rational numbers.
