Investigate the function y = 2 · 4x . What would be the effect of replacing the 2 with a 5? What would be the effect of adding +1 to the end of the equation, making it y = 2 · 4x + 1? Include sketches as a part of your investigation. Homework Help ✎
Experiment with the functions. Creating a table of values and graph for every function will help you.
