Please help me with a). I do not understand how to find the formula from the lines.
As instructed before, do the same for f(x).
Remember that you are using two-point form to find the equation(s) of the line(s).

Thank you so much for your continual help. I got the same answer using the
y = mx + b method.
Anyways should there be a limit on what x values these formulas should operate in? Because if there wasn't any, the lines will proceed to go further than the point of intersection between f(x) and g(x).
