Question

For the function given, state the starting point for a sample period:
ƒ(t) = 0.2sin (t − 0.3) + 0.1
A.(0.3,0.2)
B.(0.3,0.1)
C.(0.3,0)
D.(0.3,1)

Answer 1

What would the starting point be if your function were y=0.2sin (t − 0.3)?

Answer 2

my answer was C

Answer 3

Now if your function were 0.2sin (t − 0.3)+0.1, how would the graph differ from the previous one?

Answer 4

Unfortunately, C is not correct, because the given function has a vertical offset.

Answer 5

it would just be 0.1 different

Answer 6

so would it be B

Answer 7

So how would the resulting graph look different?

Answer 8

it would be 0.1 on the y

Answer 9

the answer would be B correct?

Answer 10

You'd move the graph of 0.2sin (t − 0.3) UP by 0.1 unit. Yes. You're correct. Very good!

Answer 11

thanks so much! i have another problem can u help with it

Answer 12

Yes. Pls post it separately from this one.

Answer 13

ok
