Question

Identify the middle line for the function: f (t) = 5sec(3t − π) + 1.
A.y=0
B.y=1
C.y=3
D.y=2
my answer was D

Answer 1

If there were no +1 in f(t) = 5sec(3t − π) + 1, identify the "middle line."

Answer 2

3?

Answer 3

No. That 3 is the frequency and does not affect the "middle line."

Answer 4

oh would it be 0 then?

Answer 5

that 3 affects the period.

Yes. the equation of the "middle line" would be y=0.

Now, what's the equation of the middle line for f(t) = 5sec(3t − π) + 1?

Answer 6

it would be y=1

Answer 7

Very good!

Answer 8

once again thanks so much!

Answer 9

My pleasure!
