Function $${C}$$ is a linear function with the given characteristics.

The $$y$$-intercept of $$C$$ is between the $$y$$ intercepts of Aand B.

The rate of change of $$C$$ is greater than the rate of change for $$A$$ and less than the rate of change for $$B$$. Draw a possible graph of Function $${C}$$.
