Question
Identify, which of the following numbers are rational or irrational. 
Hint:
Hint:
If the number under the square root is a perfect square of any integer, then the square root can be considered a rational number.
The correct answer is: YES an irrational number
Let’s say x =
Step 1 of 2:
Let’s factorise the number inside the square root i.e 27
Step 2 of 2:
Put the factorised in the square root
is a irrational number
Final Answer:
As is an irrational number so 
will also be an irrational number. Hence, is an irrational number.

Which of the following is an example of a function whose graph in the xy-plane has no x-intercepts?
In economics, the linear function is popular. It is appealing because it is straightforward and straightforward mathematical. Moreover, it has numerous useful applications.
A linear function consists of one independent variable and one dependent variable. 'y' is the dependent variable, while 'x' is the independent variable. In economics, the linear function is popular. It is appealing because it is straightforward and straightforward mathematical. Moreover, it has numerous useful applications. For example, linear functions have graphs that are straight lines.
A linear function's domain and range are typically a set of real numbers. However, there is one exception: if the function is constant (for example, f(x) = 2), the range is constrained to that constant.
