A continuación se muestran seis gráficos. Hacer clic en las pestañas para verlos. Marcar la casilla correspondiente a cada gráfico que represente una función.

Step 1: Understand the definition of a function using the vertical line test. A graph represents a function if and only if every vertical line drawn through the graph intersects the graph at most once. If a vertical line intersects the graph at two or more points, then it is not a function. Step 2: Apply the vertical line test to "Gráfico 3". "Gráfico 3" shows a parabola that opens downwards. Imagine drawing vertical lines across this graph. For any given x-value, a vertical line will intersect the parabola at exactly one point. For example, at x=0, the graph intersects at y=0. At x=1 or x=-1, the graph intersects at approximately y=-1. At x=2 or x=-2, the graph intersects at approximately y=-4. Step 3: Conclude based on the vertical line test. Since every vertical line intersects the graph of "Gráfico 3" at exactly one point, it satisfies the condition for being a function. Therefore, "Gráfico 3" represents a function. Gráfico 3 represents a function. ¡Excelente! ¿Cuál es la próxima pregunta? 📸
