    Question "State the point you know lies on each of the following functions" - Help Please

    My girlfriend is taking college algebra and asked me about these questions (see attachments). I am totally drawing a blank, the book has no examples, she has no notes and the teacher hasn't gotten back to us. I know it's gotta be easy, but it's eluding me.


    If you have any time at all and want to help a struggling college student, we would really appreciate it. =)

    Frankly, I am confused as to what you are asking. You have the correct answers.

    From the given g(4)=-2.
    Let's do part b). 1.6t=4 so t=2.5.
    Thus g(1.6(2.5))+7.68=5.68 so (2.5,5.68) is on that curve.

    Those answers were from the study guide. We didn't know the process of *getting* the answer for new questions that will be on the test. From your example I figured out the process. Thanks!
