To sketch the function

Answer to Problem 53E
Explanation of Solution
Given:
Function:
Calculation for graph:
Consider
Values of x | Values of f (x) |
0 | 4 |
1 | 2.333 |
-1 | 1.666 |
2 | 2.222 |
-2 | 0.444 |
By taking different values of x, the graph can be plotted.
Graph:
Calculation:
Intercepts:
Let
To find x intercepts, put y = 0,
So, the x intercept is (-2.594, 0).
To find y intercepts, put x = 0,
So, the y intercept is (0, 4).
Asymptotes:
Vertical asymptotes:
To find vertical asymptotes, put denominator of the given function equal to zero.
So, vertical asymptote does not exist for given function.
Horizontal asymptotes:
As the degree of numerator is larger than the degree of the denominator, the horizontal asymptote does not exist for given function.
Slant asymptotes:
To find slant asymptote, divide given function numerator with denominator using long division.
Dividend:
Divisor:
Here, quotient is
So, the slant asymptote is
