Function Number Lines
Drag the blue dot (input) left/right to see how the red dot (output) changes. Can be used like a puzzle. Try to determine the function based on how the input/output changes.
Change the function by typing a new one into the function input. (Try some like: cos(x), abs(x), x^2) Change the tick mark scale by inputting different numbers for either input or output. (e.g. can count by 1's, 5's, pi's, etc.) Change the distance between tick marks by dragging the orange mark on the input number line. (Must have 'zeros' shown) Show exact input/output values with specified number of decimals. (Change slider to alter number of decimal points shown.)
