    Linear Functions and Change; Need help!



    I need help on part a.

    I know how to find the rate of change and use the formula, but what gets me stuck is that they didn't give me the g(x) in this case. How am I suppose to find an estimate it? Thank you.

    The question gave you the function $\displaystyle g(x)$ in its geometrical form (the graph), and it wants you to use the graph to estimate the outputs of the function. From the graph, $\displaystyle g(0) \approx 0$ and $\displaystyle g(4) \approx 2$ :

    Thank you so much for your help. I was stuck on that problem for quite a well. I didn't know if I had to find the asymptote of the line g(x) in order to solve this problem. But now I can see it is much more simple than it looks.
