Explanation of Solution
Given information:
Consider the function
The function is a relation defined on two sets, that is every element of first set contains a
unique element in second set.
Domain of the function is the set of all possible input values of a function.
Range of the function is the set of possible outputs.
Consider the function
Domain is the possible x values, here
Range is the
(b)

Explanation of Solution
Given information:
Consider the graph of the function.
Consider the function
The domain values are o the
The range values are in the
The graph of the function is set of all points in the plane of the form
(c)
To Explain: the method to identify weather the given curve is a graph of a function.
(c)
![Check Mark](/static/check-mark.png)
Explanation of Solution
Given information:
Consider the graph of the function.
Vertical line test is used to verify weather the given curve is a function or not.
According to vertical line test,
Draw a vertical line on to the given curve, if the vertical line intersect the curve at only
once, then the curve is a graph of the function, otherwise not.
