The line of music which shows a translation is b.
Translation means moving.
Y=2 because if you subtract 52-22 you will get a difference of 30
Many students seem puzzled by function notation well after it has been introduced, and ask “why can’t we just write

f(x) = 3x ?”. To motivate the use of function notation and improve understanding, I advocate using multi-variable functions instead of single-variable functions in introducing this notation. My introduction usually proceeds something like this:
Step-by-step explanation:
Answer:
y=27;y=−42
Step-by-step explanation:
33−y=6;63+y=21
y=27;y=−42
I hope this helps!
