The correct answer would be B
Domain are for x-values so [0,3] and range are y-values so [2,-2]. It is not a function because there are multiple x-values for y-values. The only thing I am not sure about is whether to use brackets [ ] and/or parentheses ( ) because the graph does not use circles. Hope this helped!
You're trying to find constants

such that

. Equivalently, you're looking for the least-square solution to the following matrix equation.

To solve

, multiply both sides by the transpose of

, which introduces an invertible square matrix on the LHS.

Computing this, you'd find that

which means the first choice is correct.
Answer:
27
Step-by-step explanation:
Translation means you are shifting the line either up or down.
