- The Difference Quotient
- $\rhd$ Example 1 (3:19) (a) Let $f(x)=2x-5$, find $f(x+h)-f(x)$. (b) Let $f(x)=3x+2$, find the difference quotient $\dfrac{f(x+h)-f(x)}{h}$.
- $\rhd$ Example 2 (4:34) Let $f(x)=2x^2-x+5$, find and simplify the difference quotient $\dfrac{f(x+h)-f(x)}{h}$.
- Analyzing Graphs
- $\rhd$ The graph of a function (19:01) Given the graph of a function, find the domain, the range, pre-images and images.
