Hi there, I need help with the following questions, you don't need to have a detailed explination. Answer + a sentence is good enough, thanks!

1. The mapping that transforms y = VI to y +5 = v 21 -4 is: O (z, y) -> ( 27 +2, y +5) O (z, y) - ( 2r +4, y -5) O (I, y) - TI -2, y -5 2. Given the function f(z) =avb(x -h) + k with a domain of {r |1 2 2, z ( R] and a range of {y ly
