# Homework Help: Rearranging a function. Seems quite basic.

Hello.

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.

Hello Matty R!
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

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

I feel alot better now.
