Graphing added functions is simply adding two expressions together and graphing the result. This can be done algebraically or graphically. We have actually been graphing added functions for a while now, remember y=mx+b? This is the result of adding two equations:
- y = mx
- y = b
This is part of the Prelim Maths Extension 1 Syllabus from the topic Functions: Further, Work with Functions.
Now let’s learn to examine the relationship between the graphs of = () and = () and the graphs of = ()+ ().
