This is the graph of f(x) = 4.- 4:What is the horizontal asymptote of (x)?A. The y-axisB. The x-axisC. The line x = -1D. The line y = -1

A horizontal asymptote is a horizontal line that tells you how the functio will behave at the very edges o a graph.
The given function tends to be closer to the x-axis as x increases.
