The range of the function is equal to
Explanation of Solution
Given information:
Given function,
Calculation:
Consider the function,
To solve for the
Consider,
Therefore,
To solve for the
Consider,
The function has no x -intercepts.
Vertical asymptotes:
The vertical asymptote occurs at the point that makes the denominator of the function zero.
The denominator of the function is,
Find the vertical asymptotes,
Therefore, the vertical asymptote occurs at
Horizontal asymptotes:
The degree of the numerator and denominator are the same, the horizontal asymptote occurs at the point determined by the following equation:
The equation for the asymptote is
Sketch the graph of the function
From the graph,
The vertical asymptote at
The domain of the function is equal to
The horizontal asymptote at
The range of the function is equal to
