Answer:
A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6
Step-by-step explanation:
The diagram shows translated to the left graph of the logarithmic function.
This graph intersects the x-axis at point x = -5, hence the x-intercept is at x = -5.
This graph approaches to the vertical line. The line passes through the point (-6,0), so the equation of this vertical line is x = -6.
Therefore, correct option is A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6
