A horizontal shift refers to the transformation of a function where the graph of the function moves left or right along the x-axis. This transformation occurs without altering the shape of the graph, simply changing the input values that correspond to each output value. The direction of the shift is determined by the sign of the constant added or subtracted inside the function's argument; a positive constant shifts the graph to the left, while a negative constant shifts it to the right.
congrats on reading the definition of horizontal shift. now let's actually learn it.
