use the graph of the function f to find f(-4), f(-3), and f(-2)

  • algebra -

    We do not see the graph, so we're unable to find f(-4), etc.
    On the other hand, with the graph in hand, you could look up -4 in the x-axis, go vertically until you hit the curve then go horizontally to find the corresponding value for y, which equals f(-4) in this case.
