Students were enquired to answer a question at institution and to assert what is most important for them to succeed. One that response stood out from the rest was practice. Successful people usually are not born successful; they become successful by just hard work and perseverance. This is how you can complete your goals. as follows some question and answer examples that you could use to improve your knowledge and gain insight that will guide you to continue your school studies.

## Question:

What are the domain and range of the function below?

## Answer:

**Answer:**

Domain is the set of all real numbers

Range is the set of all real numbers.

**Step-by-step explanation:**

Given a graph with curve which has y intercept -5, and x intercept 5.

The graph is continuous at all points of x and y

We find that the graph is a straight line with positive slope of the form

x/5 +y/-5=1

Or x-y =5

The graph is defined for all values of x and y.

The domain is the set of values x can take

In the graph horizontal axis is x axis.

Hence from the graph we see that x can take values from -infinity to + infinity

Hence domain is x = R

For range, we consider the values of y as per graph.

WE find that y is taking values in the interval (-infinity, infinity)

Hence Range =R

They could potentially hopefully help the student answer the question by implementing the questions and answer examples. Then could certainly make some sharing in a group discussion and also study with the classmate in reference to the topic, so another student also have some enlightenment and still keeps up the school learning.
