2-44.

Escribe una posible ecuación para cada uno de estos gráficos. Supón que una marca en cada eje representa una unidad. Verifica tus ecuaciones en una calculadora gráfica. .

  1. 2 sections of decreasing curves, with dashed vertical line at, x, = negative 2. Left section approaches, x axis from bottom, & vertical line from the left. Right section approaches, x axis from top, & vertical line from the right.

    Observa que esta es una hipérbola

  1. Upward parabola, vertex at (0, comma negative 5), passing through the points (2, comma negative 1), & (negative 2, comma negative 1).

    Observa que el vértice es
    .

  1. Increasing curve, rises quickly, flattens out as it passes through the point (3, comma 0), and then rises quickly again.

    Observa que este es un gráfico cúbico.

  1. Increasing curve, with horizontal dashed line at, y, = negative 3. Left side of graph approaches the horizontal line from above, right side grows rapidly.

    Observa que este es un gráfico exponencial.

  1. Increasing line, passing through the points, (0, comma negative 6), & (2, comma 0).

    Observa que el punto de corte con el eje es .

  1. Increasing curve, rises quickly, flattens out as it passes through the point (negative 2, comma 3), and then rises quickly again.

  1. Upward parabola, vertex at (negative 3, comma negative 6) & passing through (0, comma 3).

  1. Downward parabola, vertex at (3, comma 6), and passes through (0, comma negative 3).

  1. Increasing curve, rises quickly, flattens out as it passes through the point (negative 3, comma negative 2), and then rises quickly again.
