Review of Transformations

Use the sliders to review transformations.

In general, if the base function is y=f(x) (where k>0), then describe each transformation. 1) y=f(x)+k 2) y=f(x)-k 3) y=f(x+k) 4) y=f(x-k) 5) y=-f(x) 6) y=f(-x) 7) y=-f(-x)

Visual Limits (L'Hopital's)

[math] \textbf{(a) Describe the type of indeterminate form (if any) that is obtained by direct substitution.}\\ \textbf{(b) Evaluate the limit using L'Hopital's Rule if necessary.}\\ \textbf{(c) Using the applet explain how the graph verifies you results.}\\ \displaystyle \large \begin{equation} \lim_{x\to 0^+} (-x \ln(x)) \end{equation} [/math]
