@DariusX @Ephemera @Hero Sorry to bother you all, but do any of you know how to do this? I'm trying to learn how because I have to do a phone call with my teacher.

I know how it's done just don't know any real world examples :/

You get paid a flat fee of $5 for babysitting. Each hour you babysit, you get $2. y=2x+5

anonymous · Answer

Well constructing a function would give you such a large window that there really is no need for an explanation if you know some algebra.
You could have a linear function or quadratic.

Linear example
-------------
y=x or 
y=3x+2

Quadratic ex
-------------
y=x^2 or
y=4x^2 + 7

All they're asking is to create one using a real world scenario, like @hennawho did
