(a)
To calculate: The domain of the function
(a)
Answer to Problem 1PRE
Solution:
The domain of the function is
Explanation of Solution
Given:
The function,
Calculation:
The domain is the all possible input for any provided function.
Here, the domain will be
(b)
The range of the function
(b)
Answer to Problem 1PRE
Solution: The range is
Explanation of Solution
Given:
The range is all the possible outputs of a given function,
Here, for
Hence, the range is
(c)
The x-intercept(s) of the function
(c)
Answer to Problem 1PRE
Solution: There is no x-intercept.
Explanation of Solution
Given:
To find the x-intercept(s), solve the equation
This is false,
Hence, there is no x-intercept.
(d)
The y-intercept(s) of the function
(d)
Answer to Problem 1PRE
Solution: The y-intercept is
Explanation of Solution
Given:
To find the y-intercept(s), evaluate
The y-intercept is 3.
(e)
The asymptotes if applicable for the function
(e)
Answer to Problem 1PRE
Solution: No asymptotes.
Explanation of Solution
Given:
Since the given function is a constant function, i.e., no curve involved.
Hence, no asymptotes.
(f)
The intervals over which the function
(f)
Answer to Problem 1PRE
Solution: Never increasing.
Explanation of Solution
Given:
Since the given function is a constant function, i.e., no curve involved.
Hence, never increasing.
(g)
The intervals over which the function
(g)
Answer to Problem 1PRE
Solution: Never decreasing.
Explanation of Solution
Given:
A function is an increasing function if the function values increase within the given interval. Similarly, a function is a decreasing function if the function values decrease within the given interval.
Since the given function is a constant function, i.e., no curve involved.
Hence, the given function
(h)
The match of the function
(h)
Answer to Problem 1PRE
Solution: Graph E.
Explanation of Solution
Given:
Since the given function is a constant function where for any value of x the output is 3,
Hence the graph will be a horizontal straight line crossing the y-axis at
The correct match will be graph E
