I have been a high school math teacher for 27 years. My students are the best! I love finding new ways to help students learn, especially as technology changes. When I am not teaching, I enjoy baking bread, trying new recipes, and spending time with my family.

If $f(x)=x+\sqrt{2-x}$ and $g(u)=u+\sqrt{2-u},$ is it true that $f=g ?$

If $ f(x) = \frac{x^2-x}{x-1} $ and $ g(x) = x $ is it true that $ f = g $?

Determine whether the curve is the graph of a function of x. If it is, state the domain and range of the function.
