Google Classroom

f is a finite function whose domain is the letters a to e. The following table lists the output for each input in f's domain.

x	a	b	c	d	e
f, left parenthesis, x, right parenthesis	1	2	3	1	2

Answer 2 questions about the function.

Build the mapping diagram for f by dragging the endpoints of the segments in the graph below so that they pair each domain element with its correct range element.
