    Quick graph questions



    Which direction/s is the graph above shifted? How many units is it shifted?



    Which direction/s is the graph above shifted? How many units is it shifted?

    You must know something more about the functions graphed here, because otherwise there is no answer to these questions. So, please, give us that missing information about the two functions.

    Nope. There are no missing functions. It is a guessing game according to the information you can find from the graph

    Well, then the question should be phrased differently. Then the question should be (you now tell me): Find functions whose graph fits these pictures.
    But the original question ("How many units is it shifted?") suggests very strongly that one knows the basic form of the graph and is only asked to determine how this known graph has been shifted. To me it sounds like you have dropped part of the context from which this problem has been taken.

    No, really. This is exactly how it was written, nothing was altered at all. Bad question, huh? That's why I posted it

    I am thinking I should probably ask my teacher for a hint on this one. Do you think there is anything in particular I should ask for?

    Thanks

    Nothing that has not already been said can be said.

    I asked my teacher how I can solve it when there are missing functions here and she asked me this and gave me the direction:





    1. How many units right is the graph above shifted? I think 2.2?





    2. How many units up is the graph above shifted? I think 2.5?

    Thanks

    The question only makes sense if there is a reference function these graphs have been shifted from. The questions as posted cannot be answered until that function is provided. Period. Finito. End of story.

    I don't disagree. However, the hidden context is usually which section in the book is being covered at the time the question is asked.

    As an educated guess, I'd say the first graph looks like the typical graph of a logarithm, and the second graph looks like the typical graph of an exponential function when the base is less than 1.

    If these were the cases, then it would appear that the first graph is shifted right 2 units, and the second graph is shifted up 3 units. I make these guesses based on my knowledge of the asymptotes of the log and exponential functions.

    I agree and had thought of that. But the point is that the OP is adamant, even after consulting with his/her teacher, that all the information is given. If questions cannot be posted that include ALL of the information relevant to the question, then the OP cannot expect to get an answer that will help.
