The similarity statement would be that all three of them have the same sides
4.16 rounded to the nearest whole is 4.2.
The equation of the piecewise function is 
<h3>The piecewise function</h3>
On the graph, we have:
- y = 3 for all x values not more than -1
- y = -1 for all values greater than 2
Hence, the piecewise function is:

<h3>The domain of the function</h3>
This is the set of input values
In (a), we have:
x ≤ -1 and x > 2
Hence, the domain is (∞, 3] u (2, ∞)
<h3>The range of the function</h3>
This is the set of output values
In (a), we have:
f(x) = 3 and f(x) -1
Hence, the range is [3] u (-1)

Choice B:
The line intersects at both points (0,-3) and (1,0)
(I can not specifically see the number on the grid if there is any but that is what I would put for the answer based on what I see)
If you want me to explain it more I can try to! :)
I hope this helps
