So, the domain of the function is
To find the x-intercept, put
So, x-intercept is
Asymptotes:
Vertical asymptotes:
To find vertical asymptotes, put the value of the given function in logarithmic part equal to zero.
So, the vertical asymptote is
Calculation for graph:
Consider
Values of x | Values of f (x) |
-1 | 0 |
0 | -0.387 |
1 | -0.613 |
2 | -0.774 |
By taking different values of x, the graph can be plotted.
Graph:
