Using Graphs & Geometry 111
Manually manipulating functions
When you have graphed a function, you can use the Pointer tool ( ) to
translate, stretch and/or rotate it by grabbing its graph. As you maneuver
the graph, its symbolic representation also changes.
You can manipulate the following types of functions:
• Linear function; y=b
• Linear function; y=ax+b
• Quadratic function; y=a(x-b)

+c
• Exponential function; y=exp(ax+b)+c
• Exponential function; y=b†exp(ax)+c
• Exponential function; y=d†exp(ax+b)+c
• Logarithmic function; y=a†ln(cx+b)+d
• Sinusoidal function; y=a†sin(cx+b)+d
• Cosinusoidal function; y=a†cos(cx+b)+d
