How i can do this step by step
if y= (x+3)^2, then (-2x-6)^2

Do you mind if you guys me with this question i’m on number 8

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.

Write a function rule for  “the output is  5 less than the input.” let  x be the input and let  y  be the output.
