@amistre64 could you help?

amistre64 · Answer

how would you define a function?  it has something to do with outputs

amistre64 · Answer

im sure one way is refered to as a vertical line test, but thats really impractical.  visually nice to conceive of, but impractical to implement

anonymous · Answer

@amistre64 a function would be when the independent and dependent variables are directly related?

amistre64 · Answer

not specific enough.  a relation is directly related as well.

a function is a relation such that there is only one dependant value for any given independant value

graphically, if we draw a vertical line and it hits the curve in more than 1 place, its not a function

function only have one value for any given input
