- Not a function
- Not a function
=================================================
Explanation:
- Relation 1 is a function because any input item in the domain leads to exactly one and only one output item in the range. If we had say 2 arrows coming from "chair", and pointing to two different outputs, then we wouldn't have a function. It's perfectly possible to use words in place of numbers when talking about functions. All that matters is that we have one input map to exactly one output.
- Relation 2 is a function for similar reasoning as relation 1. It's possible to have an output repeated and still have a function.
- Relation 3 is not a function. Why not? Because of the points (j,v) and (j,t). The input j leads to more than output (v and t at the same time). A similar issue happens with the input 's' also.
- Relation 4 is also not a function. The repeated input this time is -5 which maps to the outputs z and 'a' at the same time.
Plug -2 in for x and -5 in for y.
A. 1 - 2(-2) + 3(-5) = -10
B. - |(-2) - (-5)| = -3
C. Sqrt((-2)^2) + cubert((-5)^3) = -7
D. 1/2(-2) + 1/3(-5) = -8/3
Answer:
The answer is b.
Step-by-step explanation:
Just substitute it. :)
3(8+1)+6=33
8+1=9
9*3=27
27+6=33
