Answer:

Step-by-step explanation:
The following piecewise functions are linear functions. The graph of any of them is a line segment.
We just need to calculate the value of the function at each end specified in the brace.

Substitute x =-1 and x = 0:

Range of this piece is [-5; -2)

Substitute x =0and x = 5:

Range of this piece is [3; 13)
Therefore the range of the following piecewise function is:

Look at the picture.
Answer:
A. y = 3x.
Step-by-step explanation:Relation 2 is a straight line that does not pass through the origin, so it is a partial variation.
Answer:
1) 5/6
2) 18/10 (mixed fraction is 8)
3) 13/6 (mixed fraction is 6⅙)
