Ok thank you, But why can it be written that way? How does the plus sign get there from the equation. Can you expand on that or point me in the right direction on how to find out.
Hi All,
I am teaching my self algebra using khan academy and I've come across a problem I can't figure out. I am trying to solve composite functions and I can't figure out why a Plus sign is added to the equation, Could I be missing something that I am suppose to distrubute?
The functions...
