Answer 1

Ok, so let's start by looking at the normal graph of sin x

Answer 2

So pull that up

Answer 3

okay got it on wolfram

Answer 4

now, slightly modify it, make it like sin x + 6 what does that do to the graph?

Answer 5

well thats the vertical shift so it goes up 6?

Answer 6

good, so what letter would that be in your problem?

Answer 7

D but isnt d 30?

Answer 8

good, why?

Answer 9

wait not right

Answer 10

Answer 12

no, remember what is the max of the sine function? What is the max for this function?

Answer 13

15?

Answer 14

where did you get 15 from?

Answer 15

I'm sorry, I was looking at the wrong line. 30 is the correct answer
