To sketch the function
Answer to Problem 32E
No asymptotes
Explanation of Solution
Given:
Function:
Calculation for graph:
Consider
Values of x | Values of f (x) |
0 | 4 |
1 | 5 |
-1 | 3 |
2 | 6 |
-2 | 2 |
By taking different values of x, the graph can be plotted.
Graph:
Calculation:
Intercepts:
Let
To find x intercepts, put y = 0,
So, x intercept is (-4, 0).
To find y intercepts, put x = 0,
So, y intercept is (0, 4).
Asymptotes:
Vertical asymptotes:
To find vertical asymptotes, put denominator of the given function equal to zero.
Here, the answer is wrong. It means that, the given function does not have vertical asymptotes.
Horizontal asymptotes:
As the degree of numerator is larger than the degree of the denominator, the horizontal asymptote does not exist for given function.
Holes:
Here, the given function contains one common factor in numerator and denominator i.e.,
To find hole of the function, equate common factor equal to zero.
So, the hole of function is
