Using this virtual manipulative you may:
Graph a function
The buttons above the function window can be used to enter a fraction, an exponent, a square root, absolute value or parentheses. You may also use standard calculator notation for these.
Trace a point along the graph
A slider will appear below the graph window.
You may also use the left and right keyboard buttons to "nudge" the slider by small increments.
Dynamically vary function parameters
The expression for functions you enter may include constants named a, b, and c. After graphing the function, these constants can be dynamically varied. To do so:
To change the range of each parameter:
Change the range of values displayed in the graph
Graph multiple functions
You may graph up to three functions in the graph window. To graph more than one function:
You can express g(x) or h(x) in terms of previously defined functions. For example, enter f(x) = sin(x). Now let g(x) = xf(x). Try h(x) = 3f'(x)-2f"(x).
Restrict the domain of a function
Zoom in on a region of the graph
Draw a rectangle around the region of the graph you want to zoom in on:
