Answer:
The zero of the function is; (-4,0). The y-intercept is; (0,4). The horizontal asymptote is; y =2. The vertical asymptote is; x= -2
Step-by-step explanation:
The zero of a function is the point where the graph of the function crosses the x-axis. The y-intercept is where the graph of the function crosses the y-axis. The horizontal asymptote is a horizontal line that the function approaches but never touches or crosses it. Finally, the vertical asymptote is a vertical line that the function approaches but never touches or crosses it
