Rearranging a function. Seems quite basic.

  1. Apr 4, 2009 #1
    Hello. :smile:

    I'm having a bit of trouble with a question I've been given as part of a Maths course, and was wondering if someone could help.

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    As you can see, the function is meant to have +5 on the end, but I get -5. I don't know where I've gone wrong. I did ask the teacher if the 5/4 is just added to the y, and she nodded.

    I would appreciate any and all help with this. I know its basic, but its got me. :biggrin:

    Hello Matty R! :smile:
    She meant that you add 5/4 to the original y …

    in other words, y is now 5/4 more …

    so if y1 is the first jump, and y2 the second jump, then y2 = y1 + 5/4 :wink:

    Thank you so much. I'd never have thought of doing that. :redface:
