The x-axis ranges from negative 2 to 2 in one-unit increments. The vertical axis ranges from 0 to 5 in one-unit increments. The solid curve passes through the coordinates left parenthesis negative 1 comma 1 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 1 comma 1 right parenthesis. The dotted curve passes through the coordinates left parenthesis negative 1 comma 4 right parenthesis, left parenthesis 0 comma 0 right parenthesis, and left parenthesis 1 comma 4 right parenthesis.

Multiplying f(x) by 4 scales all y-values by 4 (e.g., f(1)=1 → 4f(1)=4), which is a vertical stretch.
