Answer:
Step-by-step explanation:
Given is the piecewise function.
The first part is increasing function y = x + 6, when x ≤ -3
The second part is decreasing function y = -x when x > -3
The above is reflection in the first graph (top one)
the correct answer will be c.
It is possible for two different inputs to give you the same output. For example, -2 and 2 produce the same result: 5.
it is not possible to derive two different outputs from the same input. This is because a) 
is a function making it impossible to have two outputs and b) for each value, if you square it, you only get one value, then adding one, making it one certain value.
40 goes into 120 3 times, so the answer would be 120 - 40.
Which leaves you with 80 people still at the party.
