Which statements are true of functions? check all that apply.
all functions have a dependent variable.
all functions have an independent variable.
the range of a function includes its domain.
avertical line is an example of a functional relationship.
a horizontal line is an example of a functional relationship.
each output value of a function can correspond to only one input value.

All functions have a dependent variable.   TRUE

All functions have an independent variable.   TRUE

The range of a function includes its domain.   FALSE

[Range refers to the set of outputs the function produces, domain the set of inputs the function accepts.  They don't really have to have anything to do with each other.]

A vertical line is an example of a functional relationship.   FALSE

[For a function, each input (x value) maps to at most one output (y value).  A vertical line has lots of ys for a single x.]

A horizontal line is an example of a functional relationship.  TRUE

[It's a constant function.]

Each output value of a function can correspond to only one input value.  FALSE

[A function can have the same output given different inputs, for example f(x)=x^2  has f(1)=f(-1) ]
