1. The problem is to understand and analyze graphs of functions. 2. A graph of a function $y=f(x)$ shows the relationship between $x$ (input) and $y$ (output). 3. Important features to consider are intercepts (where the graph crosses axes) and extrema (maximum and minimum points). 4. Intercepts: The $x$-intercept(s) occur where $y=0$, solve $f(x)=0$. 5. The $y$-intercept occurs where $x=0$, evaluate $f(0)$. 6. Extrema: Points where the function reaches local maxima or minima, found by setting the derivative $f'(x)=0$ and analyzing. 7. These features help understand the behavior and shape of the graph. 8. Without a specific function, we cannot plot or find exact points, but these rules apply generally.
