ALEKS Math - Does this machine represent a function in algebra?

How do you determine if a relation is a function? A function is defined as each input value mapping to one and only one output value. The set of input values in a function is called the domain and the set of output values is called the range. A great way to test if a relation is a function is to use the vertical line test. All algebra students need to master and understand all concepts about functions as functions are everywhere in mathematics. For more in-depth math help check out my catalog of courses.
