## On the Subject of Function Identification

Does this module *function* as intended?

This needy module will show a random graph of a function upon activation. The defuser’s goal is to find the type of the function from the graph and submit it.

### Controlling the module

- Use the left and right arrows at the bottom of the module to scroll through different types of functions.
- Click the function type to submit your answer.

The module will deactivate if you guess the function type correctly. Upon an incorrect submit, you will get a strike. The module will not deactivate.

### Important information

- Only the types of functions listed below can appear on the module.
- Logarithmic functions are
*always*in the form of $y={\mathrm{log}}_{a}x$, where $a>1$, to avoid confusion between logarithmic graphs and exponential graphs. - Exponential functions are
*never*in the form of $y=-{a}^{x}$ with $0\le a\le 1$, to avoid confusion between logarithmic graphs and exponential graphs.

### Types of functions

The module presents the following types of functions:

- Linear
- Constant
- Reciprocal
- Quadratic
- Cubic
- Goniometric
- Exponential
- Logarithmic

### Other information

- Graphs can be moved up or down.
- Graphs can be moved left or right.
- Graphs can be flipped along the x and/or y axis.
- There are only 10 graphs of each function type.
